Why do the factors of 16 are also factors of 32 and 64?

Answer 1

All numbers have factors. Some numbers have some of the same factors as other numbers. Multiples of numbers have all of the factors of numbers that are factors of them, plus some of their own. 32 is a multiple of 16 and will have all of its factors. 64 is a multiple of both 32 and 16 and will have all of their factors.

Answer 2

All factors of 16 will also be factors of all multiples of 16. Multiples of 16 will also have factors that are not factors of 16. For example, 80 is a multiple of 16, but some of the factors of 80, like 5, 10, 20, 40 and 80 are not factors of 16.

Answer 3

Yes, as 16 is a factor of 32 and 64, its factors would divide evenly into them as well.

Answer 4

1, 2, 4, 8
