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.
By finding their prime factors
The least common multiple of two primes x and y, is x * y.
You need at least two numbers to find an LCM.
You need at least two numbers to find an LCM.
Prime factorization.
You need at least to numbers to find a least common multiple.
Prime factorization.
5 and 7 are both prime numbers, so the least common multiple is 5*7=35
Prime factors of 12 are 22 and 3 Prime factors of 15 are 3 and 5 Prime factors of 22 are 2 and 11 Least common multiple = 22*3*5*11 = 660
The least common multiples means the smallest multiple of two numbers so to find a the least common multiple, you find all the multiples, and the smallest in the least common.
You need at least two numbers to find a least common multiple.
