Seven factors.
The factors of 64 are all 2s and the factors of 81 are all 3s. The greatest common factor is 1, since they have no factors in common. ■
1, 2, 4, 8, 16, 32, 64 All but 1 and 2 are composite.
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.

It is 126.
To tackle this question, you first need to break the number down into its prime factors. In this case we have 64 = 2x2x2x2x2x2 To find the greater factors, you need to multiply any combination of these. That gives us the factors as 2, 4, 8, 16, 32 and 64 Adding these up for the sum gives us 126 Thus the sum of all even factors of 64 is 126.
The factors of 64 are 1, 2, 4, 8, 16, 32 and 64. No two of them add up to 19.
The sum of all odd numbers from 1 to 64 inclusive is 4,096
there is no, because in order for it to have one, one of its factors has to be odd.
No, 32 and 64 have other factors as well.
The sum of all the positive factors of 12 is 28.
The factors of 64 are 1, 2, 4, 8, 16, 32, and 64.
The sum of the positive whole-number factors of 30 is 72.
