What is the greatest common factor of 54 and 72?

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.
