What is the Greatest Common Factor of 542

and 18?

GCF: 2

Step-by-step explanation:

there are a lot of ways to find the greatest common factor of two numbers

so, first find all the factors that give u the solution that u have

18 = 18 times 1, 2 times 9 and 3 times 6

the factors of 18 is 1, 2, 3, 6, 9, 18

542: 542 times 1 and 2 times 271

the factors of 542 are 1,2,271,542

if we see the factors of 18 and 542, the only two things that are common are 2 and 1 and 2 is greater than 1, so 2 is the GCF
