First of all both numbers are expressed as the product of primes. Prime factorization of 28 = 2 x 2 x 7 Prime factorization of 38 = 2 x 19 As it can be seen only 2 is common in prime factorization of both numbers. 2 is the only number except 1 that goes into 28 and 38. So, GCF(28, 38) = 2.
2 x 19 = 38 3 x 3 x 3 x 3 = 81
2 x 19 = 38
54*38 = 4100625 in prime exponents
As a product of its prime factors in exponents: 22*38 = 26244
The prime factorization of 38 is 2 x 19.
The prime factors of 38 are 19 and 2. Since 1 isn't prime or composite, 1 cannot be a prime factor of 38.
The GCD is 38. You can find it with a calculator, using prime factorization with exponents, or using one of the many on-line GCD calculators.You can also list the factors of both numbers and find the largest one that they have in common.
