Yes.
Apart from 1, all of the other factors of 72 are multiples of prime factors.
28, 56, 84, and all other multiples of 28 that are factors of other numbers are also divisible by 28.
yes. they are still multiples of 2
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.
All factors of a number n will be factors of any multiple of n. All multiples of a number n will be multiples of any factor of n.
2 and 5 are the prime factors that are common to all multiples of 10.
All multiples of 9 share common factors with 9.
All multiples of 3 are factors of something.
All numbers are factors (of their multiples).
Numbers ending in zero are all multiples of 10, and therefore also are multiples of 2 and 5.
30 and 60 have 2, 3, and 5 as factors, as do all other multiples of 30.
All the factors are possible.
