The first step to finding the least common multiple is breaking down the numbers into their prime factors. In this case:
13 = 13
75 = 13x5
The next step is identifying any common factors. In this case, both numbers have 13 as a factor so we can discard one, leaving us with 13 and 5. Multiply these together to find the LCM:
13x5 = 75
Thus the least common multiple of 13 and 75 is 75.
If the prime factorizations have no factors in common, the LCM is the product of them.
5 c
If none of the prime factors are in common, the LCM will be the product of the two.
the answer is 264 Prime Factorizations 33=3*11 (2 distinct prime factors) 8=23 (3 prime factors, 1 distinct)
The least common multiple of 8, 16, and 20 is 80.
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.
At least two.

The factor tree finds the prime factorization of a given number. Combining the prime factorizations of two denominators correctly will give you their least common denominator.
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.
