What is the greatest common factor of 126 and 315?

Answer 1

Well, honey, the greatest common factor of 126 and 315 is 63. It's like finding the biggest slice of cake you can share between the two numbers - in this case, it's 63. So, go ahead and slice up that math problem like a delicious dessert!

Answer 2

The greatest common factor (GCF) of two numbers is the largest number that divides both of them without leaving a remainder. To find the GCF of 126 and 315, you can use prime factorization. The prime factorization of 126 is 2 x 3 x 3 x 7, and the prime factorization of 315 is 3 x 3 x 5 x 7. The common factors are 3 and 7, so the GCF of 126 and 315 is 3 x 7 = 21.

Answer 3

To find the greater common factor (GCF) of two ( or more) numbers, factorise each number.

Hence

126

has factors of 2,3,3,7

315

has factors of 3,3,5,7

The common factors are '3' , '3' again and '7'.

Multiply together

3 x 3 x 7 =

9 x 7 = 63 The GCF of 126, & 315.

NB The '2' & '5' are NOT common to both numbers.

Answer 4

Oh, dude, the greatest common factor of 126 and 315 is 63. It's like the number that can divide both of them without leaving any remainder. So, yeah, 63 is the boss in this math party.

Answer 5

The GCF of 126 and 315 is 63.
