we have
[tex] 56+64 [/tex]
Step [tex] 1 [/tex]
Find the GCF
we know that
[tex] 56=2^{3} *7\\ the \ factors\ are=1,2,4,7,8,14,28,56 [/tex]
[tex] 64=2^{6} \\ the \ factors\ are=1,2,4,8,16,32,64 [/tex]
[tex] The \ common\ factors\ are\ 1, 2, 4, and\ 8 \\ The\ GCF is\ 8 [/tex]
Step [tex] 2 [/tex]
we know that
[tex] \frac{56}{8} =7\\ \\ \frac{64}{8} =8 [/tex]
[tex] (56+64)=(8*7)+(8*8)\\ (56+64)=8*(7+8) [/tex]
therefore
the answer is
[tex] (56+64)=8*(7+8) [/tex]
