What is the greatest common factor of 72 and 18

18

Step-by-step explanation:

The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

The factors of 18 are 1, 2, 3, 6, 9, 18

The common factors are 1, 2, 3, 6, 9, 18

The greatest common factor = 18

18

Step-by-step explanation:

72 factors=1,2,3,4,6,8,9,12,18,24,36,72

18 factors=1,2,3,6,9,18

So HCF = 18

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
