Write the sum of the numbers as the product of their GCF and anothet sum. Problem: 56+64=?
It looks like the first thing you have to find is their GCF, ya reckon ?
The factors of 56 are 1, 2, 4, 7, 8, 13, 28, and 56 .
The factors of 64 are 1, 2, 4, 8, 16, 32, and 64 .
The common factors are 1, 2, 4, and 8 .
The greatest one is 8 .
56/8 = 7
64/8 = 8
56 plus 64 = (8 times 7) plus (8 times 8)
56 plus 64 = 8 times (7 plus 8) <== that's the answer
Check it out:
56 plus 64 = 120
8 times (7 plus 8) = 8 times 15 = 120 yay!
we have
\(56+64\)
Step \(1\)
Find the GCF
we know that
\(56=2^{3} *7\\ the \ factors\ are=1,2,4,7,8,14,28,56\)
\(64=2^{6} \\ the \ factors\ are=1,2,4,8,16,32,64\)
\(The \ common\ factors\ are\ 1, 2, 4, and\ 8 \\ The\ GCF is\ 8\)
Step \(2\)
we know that
\(\frac{56}{8} =7\\ \\ \frac{64}{8} =8\)
\((56+64)=(8*7)+(8*8)\\ (56+64)=8*(7+8)\)
therefore
the answer is
\((56+64)=8*(7+8)\)
