Question

grestest common factor of 12 and 18

Answer 1

Answer:

Greatest common factor of 12 and 18 is 6.

Step-by-step explanation:

The greatest common factor is the biggest number among the common factors of the numbers.

First, we shall prime factorize the numbers. That is we can write each number as the product of primes.

$12=2^2\times 3\\\\18= 2\times3^2$

Then the greatest common factor(GCF) is obtained from the common primes involved in the prime factorization of the numbers.

GCF$=2\times 3=6$.
