First, you need to figure out the factors of 30, 75, and 120:
The factors of 30 are 1,2,3,5,6,10,15, and also 30. The factors of 75 are 1,3,5,15,25, and also 75. The factors of 120 are 1,2,3,4,5,6,8,10,12,15,20,24,30,40,60, and also 120.
Then you need to see what factors these numbers have in common. 30, 75, and 120 have the factors 1, 3, and 5 in common. Out of all of these numbers what is the greatest number that all three of these numbers have in common? If you said 5, you are correct.
So the greatest common factor of 30, 75, and 120 is 5!
I hope this answer helped you understand this problem.

10 and 120 30 and 40
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 120, 150, and 150 is 30
Too easy, 30
