The GCF is 4.

One way to determine the least common multiple of three or more numbers is to find the least common multiple of two numbers at a time, reducing the quantity of numbers you are working with, until you are down to the final two numbers. The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 9 and 12 is 3, so their least common multiple is 9 x 12 divided by 3 = 36. Now, we have simplified the problem to determining the least common multiple of 16 and 36. The greatest common factor of 16 and 36 is 4, so the least common multiple is 16 x 36 divided by 4 = 144. Therefore, the least common multiple of 9, 12, and 16 is 144. The LCM of 912 and 16 is 912. The LCM of 9, 12 and 16 is 144.

The greatest common factor (GCF) of 12, 16, and 32 is: 4.

The LCM of 8, 12, and 16 is 48.

The Greatest Common Factor of 16 and 12 is 4.
