Sunday 1 October L.O. - To identify common factors, common multiples and prime numbers.

Here is one of the possible ways!

This morning we are going to be looking at factors of numbers This morning we are going to be looking at factors of numbers. Let’s start off by finding out what you already know… What is a factor? How can we check if a number is a factor or not?

To put it simply, a factor is a number that divides exactly into another number. The factors of 12, for example, are 1, 2, 3, 4, 6 and 12. Factors can be shown in pairs. The factors of 12 can be shown: 1 and 12 1 x 12 = 12 2 and 6 2 x 6 = 12 3 and 4 3 x 4 = 12 Each pair multiplies to make 12.

20 Let’s use 20 as an example… 20 x 1 So an easy way to work out the factors of a number is to use your times tables knowledge! Let’s use 20 as an example… 20 20 x 1 So we can say that 20 has 6 factors; 20, 10, 5, 4, 2 and 1 10 x 2 5 x 4

Have a go at working out the factors of these numbers with the person sitting next to you. 15 30 50
