The GCF of 75 and 40 is 5. To figure out the GCF of something, you can simply follow these steps:
Step 1: Find the factors of the two numbers. The numbers have no factors greater than themselves. We can stop at 40 on each, though, because 40 is the lowest number.
75: 1, 3, 5, 15, 25. (75 is one too [obviously], but we stopped at 40.)
40: 1, 2, 4, 5, 8, 10, 20, 40.
Step 2: Find all of the COMMON factors. The greatest one is the GCF.
1, and 5.
1 < 5.
GCF=5
The GCF is 5.
The GCF is 1.
The GCF of 40, 50, and 75 is 5.
The GCF is 5.
The GCF is 5.
The GCF is 5.
The GCF is 75.
If you mean 300 and 450 then the GCF is 150
