All of the numbers less than 100 (except for -1, 0 and 1) have prime factors. I suspect you left some qualifying information out of your question.
If you're allowed to repeat factors, 2 x 2 x 2 x 2 = 16. If not, no number less than 100 has more than 3 distinct prime factors.
Just 32.

By definition, a prime number has exactly two factors. So, there are no prime numbers with exactly three factors.
All whole numbers less than 100 (except 0 ) have eight or more factors ( 1 = 1x1x1x1x1x1x1x1 and so on). But I'm assuming you're trying to asking the same question except with a 'prime' infront of factors. The answer is zero as if we consider the smallest prime no. viz 2, multiply it 8 times (=256) is greater than 100.Hence, zero whole numbers less than 100 have eight or more prime factors.
If you count that as six factors, then you also have to count 64.
It is 97 which has only two factors because it is a prime number
30, 42, 66, 70 and 78.
