Best Answer

The greatest common factor (GCF) of 45, 75, and 120 is the largest number that divides each of the numbers evenly. To find the GCF, you can first identify the prime factors of each number: 45 = 3 x 3 x 5, 75 = 3 x 5 x 5, and 120 = 2 x 2 x 2 x 3 x 5. Then, you can determine the common prime factors among the numbers, which are 3 and 5. Finally, multiply these common prime factors together to find the GCF, which is 15.
