16 is a number that has four identical even factors.
A number that has only one and itself as factors is a prime number and so therefore it can't have four other identical factors.
A natural number that is NOT a perfect square has an even number of factors. 10=1x10 2x5 four 36=1x36 2x18 3x12 4x9 6
Yes. An even number will always have as it's factors, itself, 1, 2 and another number. So the minimum number of factors for an even number other than 2 is four.
There are four odd numbers less that 100 that have 6 factor. This does not compare with even numbers that have 12 factors!
