Answer:
-7
Step-by-step explanation:
7.
step-by-step explanation:
the coefficient multiplies the variable.
it is -7.
So,
First, we find the prime factored form (P.F.F.) of 65 and 91.
P.F.F. of 65: 5 * 13
P.F.F. of 91: 7 * 13
Find the common numbers
13
13 = G.C.F.
Note: This method works for finding any G.C.F. (find common primes)
Answer: not all
