Answer:

b. 60

Explanation:

The list of factors is 2, 3, 5, 7. The list of common factors is 2, 3, 5. The lowest exponents on those factor are ...

2^2 × 3^1 × 5^1 = 60

The GCF of 720 and 2100 is 60.

_____

Additional comment

You can verify this using Euclid's method of finding the GCF.

2100/720 = 2 r 660

720/660 = 1 r 60

660/60 = 11 r 0 . . . . 60 is the GCF

Find the remainder from the division. If it is zero, the divisor is the GCF. If it is non-zero, replace the largest number with the remainder, and repeat.
