2 and 3
The factors of 72 that are prime numbers are 2, 3, and 5. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves without leaving a remainder. In the case of 72, it can be broken down into the prime factors 2^3 * 3^2, where 2 and 3 are the prime factors.
2, 3 and 7. 294 = 2 x 3 x 72
As a product of its prime factors: 2*2*2*3*3 = 72
2 and 6 are prime factors of 72 2 times 6 times 6 = 72
The Fundamental Theorem of Arithmetic states that every number has exactly one, unique factorization of potentially non-unique prime numbers. Since the prime factorization of 72 is 2*2*2*3*3, we conclude that 72 is coprime with all other prime numbers, so there is no solution.
2 x 2 x 2 x 3 x 3 = 72
The prime factors of 72 are 2x2x2x3x3 (or 23 x 32).
98 is an even number, thus it is divisible by 2; 98/2 = 49. 49 is simply 72. Since both 2 and 7 are prime numbers, the prime factorization of 98 is 2 X 72.
For 64: 2 For 72: 2 and 3
To find what prime numbers are factors of 72, start with any two factor pairs of 72 and keep factoring the composite numbers until all the factors are prime. For example: 2 x 36 2 x 2 x 18 2 x 2 x 2 x 9 2 x 2 x 2 x 3 x 3
The two factors 2 and 36 go into 72.
