To find the GCF of 36, 42, and 54, we must find the prime factors of all of the 3 numbers.

36=12*3=4*3*3

42=6*7=2*3*7

54=6*9=2*3*3*3

For the GCF, you must include any number that is a factor of EVERY number in the list, and you write it the least amount of times that it shows up. Only 2 and 3 are factors of all three of the numbers you listed. The least 2 shows up is 1 time, and the least 3 shows up is one time.

So the GCF is 2*3=6
