As a product of its prime factors: 2*2*5*5 = 100
There is only one prime number which is even - that is 2 - and it also happens to be less than 100. All other prime numbers are odd.
As a product of its prime factors: 5*73 = 365
-2
Numbers under 100 that have 12 factors must be in the form of ( p_1^{11} ) or ( p_1^3 \times p_2^2 ), where ( p_1 ) and ( p_2 ) are distinct prime numbers. The prime factorization of 12 is ( 2^2 \times 3 ). Thus, the numbers under 100 with exactly 12 factors are ( 2^{11} = 2048 ) and ( 2^3 \times 3 = 24 ).
