what is the difference between a GCM and a LCM?

⚑ Flag

GCM -- greatest common multiple is the largest positive integer that divides the numbers without a remainder. For example, the GCM of 6 and 9 is 3.LCM -- least common multiple is the smallest positive integer that is a multiple of the numbers. For example, the LCM of 3 and 7 is 21.Hope that helped

GCM is known as the greastest common multiple. and LCM is know as the least common multiple. what they have in common is the the common multiple part. just remember that G is greatest and L is least.

The GCM, or Greatest common multiple, and LCM, or Least common multiple, are opposites of each other. These terms are used when you are comparing two numbers, or searching for factors of two numbers. GCM is not usually discussed, but rather the GCF, or greatest common factor. This is the largest number that can be divided into evenly two numbers. For example: If I was comparing 24 and 36, the GCF between the two of them would be 12. It is the largest factor that can be divided evenly into both of them (into 24 twice, and 36 three times).
