Question

What is the greatest common factor of 19x7 and 3x5?

Answer 1

Answer:

GCF =   $x^{5}$.

Step-by-step explanation:

Given : 19 $x^{7}$ , 3$x^{5}$ .

To find : What is the greatest common factor

Solution : We have given that 19 $x^{7}$ , 3$x^{5}$ .

The greatest common factor is the product of the highest common factors in each number.

We can write $x^{7}$  as  $x^{5}$ * $x^{2}$

Factor of 19$x^{7}$ = 1 , 19 ,  $x^{5}$ , $x^{2}$ .

Factor of 3$x^{5}$ .= 1 , 3,  $x^{5}$.

So, GCF = 1 ,  $x^{5}$.

Therefore,  GCF =   $x^{5}$.

Answer 2

Simple,

first find what 19*7 and 3*5 is,

19*7=133
and
3*5=15

Factors in 133:
1,7,19,133

Factors in 15:
1,3,5,15

The GCF of 133 and 15 is 1. You can't simplify/reduce it anymore.
