Prime factorization of 40 = 2x2x2x5 Prime factorization of 100 = 2x2x5x5
64 and 96 have the longest prime factorizations in that range. If you're asking about distinct prime factors, quite a few are tied with three.
1 is not a prime number, so it wouldn't be present in any prime factorization. Prime numbers don't really have factorizations, that is, the factorization is the number itself. There are prime numbers greater than 100.
The prime factors of 100 are 2 and 5 Prime factorization of 100: 2 x 2 x 5 x 5 or 2^2 x 5^2

100 is not prime
2 x 5 x 7 = 70 2 x 2 x 5 x 5 = 100 2 x 2 x 5 x 5 x 7 = 700, the LCM
well 100 isn't prime...
