What whole numbers are factors of themselves?
All whole numbers are factors of themselves since
a factor is any integer times another integer that equals the
number.
So, 12 can be factored to 2x6 = 12, 3x4 = 12, and 1x12 = 12.
Since
1x12 = 12, 12 and 1 are factors of 12, so 12 is a factor of 12.
Since
all whole numbers (n) can be written as n*1 = n, all whole
numbers
are factors of themselves.
