What is the gcf of 84 105 and 126?

Answer 1

Well, honey, the greatest common factor (GCF) of 84, 105, and 126 is 21. It's like finding the biggest piece of cake you can share among those three numbers without anyone throwing a fit. So, grab a fork and enjoy that GCF goodness!

Answer 2

The greatest common factor (GCF) of 84, 105, and 126 is 21. To find the GCF, you can first find the prime factorization of each number: 84 = 2^2 * 3 * 7, 105 = 3 * 5 * 7, and 126 = 2 * 3^2 * 7. Then, identify the common prime factors among the numbers and multiply them together to get the GCF, which in this case is 3 * 7 = 21.

Answer 3

Oh, dude, the Greatest Common Factor (GCF) of 84, 105, and 126 is 21. It's like the cool kid that all these numbers can hang out with without any drama. So yeah, 21 is the number that can divide these three numbers without any leftovers.

Answer 4

Prime factorization of:

84 = 2 x 2 x 3 .......... x 7

105= ..........3 x ......5 x 7

126= 2 x .. ..3 x 3 x...... 7

==================

GCF= ..........3 x ...........7 = 21

Answer: The GCF of 84, 105 and 126 = 21
