There are no prime numbers anywhere that are divisible by 2 and 7.
All of the numbers from 1 to 100 are the factors in the set of numbers from 2 to 100.
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 ).
The prime numbers (factors) of 100 are: 2 and 5
The prime factors of 100 are: 2, 5
2 and 5
They are all the prime numbers from 2 to 97 that have only two factors
It is: 100
All composite numbers have more than 2 factors but prime numbers have only 2 factors
1,2,4,5,10,20,25,50,100 2 and 5 are prime.
As a product of its prime factors: 2*2*5*5 = 100
As a product of its prime factors: 2*2*5*5 = 100
