Find the GCF 32 , 60

$32$ , $60$

Step 1

Find the common factors for the numerical part:

$32, 60$

Step 2

The factors for $32$ are $1, 2, 4, 8, 16, 32$ .

The factors for $32$ are all numbers between $1$ and $32$ , which divide $32$ evenly.

Check numbers between $1$ and $32$

Find the factor pairs of $32$ where $x \cdot y = 32$ .

$\begin{array}{c} x & y \\ 1 & 32 \\ 2 & 16 \\ 4 & 8 \end{array}$

List the factors for $32$ .

$1, 2, 4, 8, 16, 32$

Step 3

The factors for $60$ are $1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60$ .

The factors for $60$ are all numbers between $1$ and $60$ , which divide $60$ evenly.

Check numbers between $1$ and $60$

Find the factor pairs of $60$ where $x \cdot y = 60$ .

$\begin{array}{c} x & y \\ 1 & 60 \\ 2 & 30 \\ 3 & 20 \\ 4 & 15 \\ 5 & 12 \\ 6 & 10 \end{array}$

List the factors for $60$ .

$1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60$

Step 4

List all the factors for $32, 60$ to find the common factors.

$32$ : $1, 2, 4, 8, 16, 32$

$60$ : $1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60$

Step 5
