The whole number factors of 63 are numbers that divide evenly into 63 without leaving a remainder. To find these, you need to test each whole number up to and including 63 to see if it divides 63 evenly.
Here's the list of whole number factors of 63:
1 is a factor of every number.
3 x 21 = 63, so 3 and 21 are factors.
7 x 9 = 63, so 7 and 9 are factors.
And of course, 63 is a factor of itself.
The factors do not include 2 since 63 is an odd number and cannot be evenly divided by 2.
Therefore, the correct list of whole number factors of 63 is:
{1, 3, 7, 9, 21, 63}
