This week in my maths focus group I learned about factors. I learned what they are and how to find them. For example the number 15, factors would be numbers that can be multiplied to equal 15, the factors of 15 are 1, 3, 5, 15. How to identify is take 3525, for example if your thinking 3 is a factor check that by adding all the digits together like 3 + 5 + 2 + 5=15, and that can be divided by 3 so 3 is a factor of 3525.
