To find the prime factorization, start with any two factor pairs of a number and factor until all factors are prime.
2 x 36 = 72
2 x 2 x 18
2 x 2 x 2 x 9
2 x 2 x 2 x 3 x 3 is the prime factorization of 72.
145 = 51 x 291
Index form means using exponents. Exponents are just a way of notating repeated factors. The prime factorization of 72 is 2 x 2 x 2 x 3 x 3 The prime factorization of 72 is 2^3 x 3^2
2 x 5^2 = 50
Since 72 is a factor of 144, its entire prime factorization will be contained in the prime factorization of 144.
Index form means using exponents, which are a way of notating repeated factors. The prime factorization of 72 is 2 x 2 x 2 x 3 x 3 The prime factorization of 72 is 2^3 x 3^2
23*32 = 72
The prime factorization of 147 using exponents is 3 X 72.
23 x 32 = 72
49 = 72
23 x 32 = 72
49 = 72
72 * 112
23 x 32
As a product of its prime factors in exponents: 23*32 = 72
23 x 32
3 x 72
It is: 72*11 = 539
