Question

Complete the following.(a) Find the greatest common factor (GCF) of 63 and 36.хGCF = 0(b) Use the GCF to factor 63 -36.63 – 36 = (-X

Answer 1

Answer:

a) The GCF of 63 and 36 is 9

b)

$63-36=9\times(7-4)$

Explanation:

a) To find the GCF of 63 and 36, we do the following:

Write 63 and 36 as follows:

$\begin{gathered} 63=3\times3\times7 \\ 36=2\times2\times3\times3 \end{gathered}$

The common factors are:

$3\times3$

Therefore, the Greatest Common Factor (GCF) is 9

b) To find the factor 63 - 36

$63-36=9\times(7-4)$
