Answer:

Answer is option D-18.

Step-by-step explanation:

We have to find the greatest common factor of 54 and 72.

To find the solution we get the factors of each number first.

Factors of 54=2×3×3×3

Factors of 72=2×2×2×3×3

Here we can see that common factors out of these two numbers are =2×3×3 =18

Answer:

18.

Step-by-step explanation:

Write the 2 numbers as prime factors:-

54 = 2*3*3*3

72 = 2*2*2*3*3

Picking out the common factors, note that there is one pair of 2's and 2 pairs of 3's so the GCF is 2*3*3 = 18.
