How do you find the GCF of #21x^2y, 63xy^2#?

Answer 1

Nova Allen

21xy

factorize 21, we get = #3xx7#

factorize 63, we get = #3xx3xx7#

highest common factor between #x^2 , x = x#

highest common factor between #y, y^2 = y#

GCF = #3xx7xx x xx y#

To find the greatest common factor (GCF) of 21x^2y and 63xy^2, you first identify the common factors of the coefficients (21 and 63), which is 21. Then, consider the variables x and y. Both terms have x and y as common variables, with the lowest power of x being 1 and the lowest power of y being 1. Thus, the GCF is 21xy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
