Answer:

19 is the GCF

Step-by-step explanation:

Hi there~!

We just need to look for the common thing in both monomials. Since both of them have 19 in them, that is the GCF.

We can always use the listing method and list the factors of 38m and 57 n, but we can immediately see that 19mn and 9mn can be ruled out visually because

1. These numbers aren't divisible by mn
2. These numbers aren't divisible by 9

[tex]\therefore\;\;\Large\underline{\boxed{\sf{GCF=19}}}[/tex]

Hopefully, you understand this topic better now!

• The GCF is the greatest common factor
• To find it use the listing method and list every factor of both numbers

Good luck.
