JudyThe GCF of 120 and 200 is 40
One of the simplest ways to work out the gcd of 2 numbers is to take their prime factors, and multiply together the ones each number has in common. In this case,
120=2x2x2x3x5, 200=2x2x2x5x5
they have three 2's and one 5 in common, highlighted in bold above, and 2x2x2x5=40.
