What are the common multiples of two numbers?
Multiplesthat are common to two or more numbers are said to be common multiples. E.g. Multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, …. Multiples of 3 are 3, 6, 9, 12, 15, 18, …. So, common multiples of 2 and 3 are 6, 12, 18, …. Example 2.
How to calculate the least common multiple of 2 and 9?
Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor. Least Common Multiple of 2 and 9 with GCF Formula The formula of LCM is LCM (a,b) = (a × b) / GCF (a,b).
