The monomials are - 42x3y3, 21x3y and 84x4y4.

Completely factor each expression.

- 42x3y3 = - 2 · 3 · 7 · x · x · x · y · y · y

21x3y = 3 · 7 · x · x · x · y

84x4y4 = 2 · 2 · 3 · 7 · x · x · x · y · y · y · y

 The GCF is the product of the common prime factors.

The GCF of - 42x3y3, 21x3y and 84x4y4 is 3 · 7 · x · x · x · y or 21x3y.
