Hi, we are two of Mr N’s maths pupils. Last week we were studying factors, prime numbers and composite numbers. To start us off, we found factors of different numbers such as:

2 times 30

3 times 20 Altogether there are 12 factors.

4 times 15

5 times 12

6 times 10

Then we found the common factors (factors that are the same between two numbers)

Afterwards we were learning about prime and composite numbers.If you don’t know what a prime number is it is a number which has only two factors and a composite number is when it has more than two factors. Here are some prime numbers to 10; 2,3,5,7.
