The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. If you have only one number - whether or not it is a prime - you cannot have a least COMMON multiple.
The least common multiple of two different prime numbers is the product of those two prime numbers.
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.
The Least Common Multiple of 8, 242 is 968.
The Least Common Multiple of 48, 72 is 144.
The Least Common Multiple of 75, 105 is 525.
Their product.
The Least Common Multiple (LCM) for 13 & 9 is 117.
The greatest common multiple is an infinite amount and not very practical for problem solving. The least common multiple of two prime numbers is their product.
The least common factor of any set of positive integers is 1. The least common multiple of relatively prime numbers is their product.
When they have no common prime factors.
The least common multiple (LCM) of 5 and 12 is 60.
