Question

The sum of 55+66 as the product of their gcf and another sum

Answer 1

55 + 66 = 121
The GCF of 55 and 66 is 11.
11 x 11 = 121

Answer 2

$55+66=121 \\\\ 55|5 \\11|11 \\1 \\\\ 55=5*11 \\\\ 66|6\\11|11\\1 \\\\66=6*11 \\\\ G.C.F(55;66)=11 \\\\ 11*x=121 \\\\ x=3+8 \\\\ \boxed{11*(3+8)=121}$
