Factors, Multiples, Primes

Factors & Multiples 

Factors are numbers you multiply together to get other numbers. 

So for instance 2 and 5 and factors of 10, because 2 x 5 = 10 

The other factors of 10 are 1 and 10, because 1 x 10 = 10

There are no other factors of 10 because no other numbers divides evenly into it. 

Some numbers have a lot of factors. For example, how many factors of 100 can you find?
