All numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. On the list of common multiples, one number is the smallest. This is the least common multiple.
All numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. The smallest of these is known as the least common multiple. Common multiples of 3 and 4 include 12, 24, 36 and so on. The LCM of 3 and 4 is 12.
The common multiples of 3 and 12 are the infinite set of numbers that are multiples of 12, which is the least common multiple of 3 and 12. The set is 12, 24, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, and so on.
There is no such thing. If you multiply any two numbers, you'll have a number that is a multiple of both. This product won't necessarily be the LEAST common multiple, but it is a common multiple nonetheless.
There is not a least common multiple of 32 because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. Some multiples of 32 are 32, 64, 96, 128, 160, 192, 224, and 256. The least common multiple of 4 and 32 is 32. The least common multiple of 25 and 32 is 800. The least common multiple of 12 and 32 is 96.
