See a solution process below:

Explanation:

Find the prime factors for each number as:

64 = 2 xx 2 xx 2 xx 2 xx 2 xx 2

32 = 2 xx 2 xx 2 xx 2 xx 2

Now identify the common factors and determine the GCF:

64 = color(red)(2) xx color(red)(2) xx color(red)(2) xx color(red)(2) xx color(red)(2) xx 2

32 = color(red)(2) xx color(red)(2) xx color(red)(2) xx color(red)(2) xx color(red)(2)

Therefore:

"GCF" = color(red)(2) xx color(red)(2) xx color(red)(2) xx color(red)(2) xx color(red)(2) = 32
