What is the greatest common multiple of 16 and 20?
Answer: Infinity or there is none.One common multiple of 16 and 20 is 320. If you double it, which is 640, you have a larger common multiple. If you double it again, which is 1320, you have an even larger common multiple. You can continue doubling it forever, so there is no greatest common multiple, or it can be said to be infinite.The greatest common multiple of any set of numbers is infinite.
What is a factor of 320?
