What is the gcf of 42 and 70 and 84?

Answer 1

Oh honey, the greatest common factor (GCF) of 42, 70, and 84 is 14. It's like finding the least common denominator at a family reunion - you just gotta pick the biggest number that all of them can agree on. So, 14 it is, no need to overcomplicate things.

Answer 2

Oh, dude, the greatest common factor (GCF) of 42, 70, and 84 is 14. It's like the cool kid that all these numbers can hang out with and still be divided evenly by. So, yeah, 14 is the GCF for this trio of numbers.

Answer 3

To find the greatest common factor (GCF) of 42, 70, and 84, we first need to find the prime factorization of each number.

42 = 2 x 3 x 7 70 = 2 x 5 x 7 84 = 2 x 2 x 3 x 7

Next, we identify the common prime factors among the three numbers, which are 2 and 7.

Finally, we multiply these common prime factors together to find the GCF: GCF(42, 70, 84) = 2 x 7 = 14.

Answer 4

The factors of 42 are:

1, 2, 3, 6, 7, 14, 21, 42

The factors of 70 are:

1, 2, 5, 7, 10, 14, 35, 70

The factors of 84 are:

1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

The common factors are:

1, 2, 7, 14

The Greatest Common Factor (GCF) is:

14
The GCF is: 14
