120 = 2^3 x 3 x 5

48 = 2^4 x 3

112 = 2^4 x 7

gcf = 2^3 = 8

It's 8.

You can find it by looking at the prime factors of the numbers.

120's prime factors are

2³ • 3 • 5

48's prime factors are

2⁴ • 3

112's prime factors are

2⁴ • 7

The largest one of these factors that they all have in common is

2³ = 2 • 2 • 2 = 8
