All of them. Different numbers have different numbers of factors.

All factors are whole numbers and all whole numbers are rational numbers (a rational number is one which can be expressed as one integer over another integer, and whole numbers can be expressed as themselves over 1), thus all factors are rational numbers and so all greatest common factors are rational numbers. The set of whole numbers is a [proper] subset of the set of rational numbers: ℤ ⊂ ℚ
That's a little redundant, since all factors are whole numbers. Factors are the numbers that multiply together to get a product. In the sentence 4 x 3 = 12, 4 and 3 are factors of 12; two whole number factors of 12.

Whole no are the number which begin from 0 Factors of 75 are 5x5x3 All the numbers are whole numbers.
The number 1 and the prime number itself.

The who number factors of 8 are 1, 2, 4, and 8.
There are exactly two whole number factors of any prime number. The first factor is '1'. The other factor is the prime number itself.

One and the number itself.
Prime factorization
All numbers have factors. The whole number factors of a composite number are the integers that combine in a multiplication sentence to make that number. In the sentence 5 x 6 = 30, 5 and 6 are factors of 30.
