Question

Find the GCF of -10 c^2d and 15 cd^2 .
A) -5c^2d^2
B) -5cd
C) 5cd

Answer 1

Answer: The answer is (C) 5cd.

Step-by-step explanation: We are given to find the G.C.F of the following two expressions:

`-10c^2d~~~\textup{and}~~~15cd^2.`

The two expressions can be written as

`-10c^2d=-1* 2* 5* c * c* d,`

and

`15cd^2=3* 5* c* d* d.`

Therefore, the greatest common factor (G.C.F.) is

`G.C.F.=5* c* d=5cd.`

Thus, the answer is 5cd.
