See a solution process below:

Find the prime factors for each number as:

$3 = 1 \times 3$ $3 = 1 xx 3$

$5 = 1 \times 5$ $5 = 1 xx 5$

Now identify the common factors and determine the GCF:

$3 = 1 \times 3$ $3 = color(red)(1) xx 3$

$5 = 1 \times 5$ $5 = color(red)(1) xx 5$

Therefore:

$GCF = 1$ $"GCF" = color(red)(1)$
