# How do you find the GCF of 13c, 25d?

Apr 6, 2018

The GCF is 1.

#### Explanation:

$13 c$, $25 d$:

First, GCF means Greatest Common Factor.

Let's split this up:

The factors of $13$ are $1$ and $13$.

The factors of $25$ are $1$, $5$, and $25$.

As you can see, the only factor (and the greatest) they have in common is $1$.

$c$ and $d$ again, only have $1$ in common, so the GCF is 1.

Hope this helps!
