the prime ladder and factor tree has help me if the sum of all the digits is divisible by 3 the number is also divisible by 3 it help us see if the number are divisible by 3,5,2,7,11

1.The divisibility test help us find a number prime factors. 2.The HCF is a number that is the largest factor of two numbers. 3.Prime factorisation uses index notation.

1)For the factor tree we can only use prime factors and not anything else 2)max possible of HCF is A 3)the divisibility test is a way to find the prime factorisation of the number using easier ways

1. Even numbers can be divided by 2 and numbers that end with 0 and 5 can be divided by 5 2. You have to use prime numbers to do prime factorisation. 3. The smallest number between the 2 numbers we are comparing is the largest common factor.

1. Divisibility test is used for checking if a number is prime or composite. The numbers are 2, 3, 5, 7, 11. 2. 0 and 1 are neither prime nor composite numbers 3. HCF is known as the highest common factor which is the highest multiple that the two numbers can be divided by.

-if A is smaller than B, the biggest HCF can only be A. -we can use a factor tree to do prime factorisation -the index tells you how may times you multiply the base

1. I learnt that we can use the factor tree for prime factorisation. 2. I learnt that the HCF is the largest positive integer that divides the number without a remainder. 3. We can use HCF and LCM concept to solve word problems.

1. If the last digit of any number is a even number, it can be divided by 2.(Divisibility Tests) 2. The factor tree can be used to find the prime factors of a prime number.(Prime Factorisation) 3. List out all the factors of both numbers, then summarise the numbers.(HCF)

1. HCF is the largest factor that is common 2. There are 2 ways to do prime factorization, tree and ladder method 3. How to make a number into index notations

1. The divisibility test if useful if you are not that good in Dividing 2. When working on Prime factorization we must use index notation. 3. Eg, If A is Smaller then B , then the max possible size of HCF is A

1. To find out if a number is prime, just divide it by 2, 3, 5, 7 and 11. 2. Composite numbers can be divided by 1, itself and other number/numbers. 3. Highest Common Factor is the highest common factor shared between two numbers.

Divisibility test - is a super easy way to find out the prime factorization of a certain number Prime factorization - is a process of expressing a composite number as a product of a prime number HCF - the HCF of two or more non-zero integers is the largest integer that divides the number with no remainder

-A prime number cannot be divided by 2,3,5,7 and 11 -The Factor Tree and Repeated Division -Divide both numbers by the same common factor, the largest is the HCF and the factor must be lower than the number to divide.

Divisibility tests ->Divisibility test help me find prime factors. Prime factorisation ->Use the tree or ladder method to solve prime factorisation. HCF ->Use the ladder or tree method to find the HCF of numbers.

1. You can use factor trees or repeated division to help you in Prime Factorisation. 2. The highest possible common factor is the smaller number. 3. The divisibility test can help you to figure which numbers are prime and which are composite?

1)The repeated division(prime ladder) and the factor tree had helped me to find the prime factorisation of a number. 2)The numbers of the divisibility test are all prime numbers. 3)The highest common factor is the highest number that is common of two or more numbers.

1) Any even number is divisible by 2 2) The HCF of a number cannot be higher than that number itself 3) There are many different ways of figuring out which numbers are prime numbers.

ReplyDelete2. Composite numbers can be divided by 1, itself and other number/numbers.

3. Highest Common Factor is the highest common factor shared between two numbers.

1. The highest factor of a number is itself.

ReplyDelete2. The HCM cannot be lower than the LCM.

3. HCF stands for Highest Common Factor.

There isn't an HCM

DeleteDivisibility test - is a super easy way to find out the prime factorization of a certain number

ReplyDeletePrime factorization - is a process of expressing a composite number as a product of a prime number

HCF - the HCF of two or more non-zero integers is the largest integer that divides the number with no remainder

"as a product of prime factors"

Delete"largest integer that is A FACTOR ...."

1. prime factorisation is done by dividing the number by a prime integer which is a factor of the number.

ReplyDelete2. how to use a factor treee

Delete3.the divisibility test is great for shorting out prime numbers

-A prime number cannot be divided by 2,3,5,7 and 11

ReplyDelete-The Factor Tree and Repeated Division

-Divide both numbers by the same common factor, the largest is the HCF and the factor must be lower than the number to divide.

please redo point 1.

Deletewhat about the factor tree and repeated division? What to take note of?

the last point must be more concise as well.

Divisibility tests

ReplyDelete->Divisibility test help me find prime factors.

Prime factorisation

->Use the tree or ladder method to solve prime factorisation.

HCF

->Use the ladder or tree method to find the HCF of numbers.

"use the tree or ladder method to PERFORM prime factorisation"

Delete1. You can use factor trees or repeated division to help you in Prime Factorisation.
