Least common multiple (LCM) of 6 and 9 is 18. 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.
How to find the LCM of 6 and 9?
The instructions to find the LCM of 6 and 9 are the next: 1. Decompose all numbers into prime factors 2. Write all numbers as the product of its prime factors 3. Choose the common and uncommon prime factors with the greatest exponent 4. Calculate the Least Common Multiple or LCM
Which is the formula for the least common multiple?
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b). We need to calculate greatest common factor 6 and 9, than apply into the LCM equation. Least Common Multiple (LCM) of 6 and 9 with Primes. Least common multiple can be found by multiplying the highest exponent prime factors of 6 and 9. First we will calculate the prime factors of 6 and 9.
What are the prime factors of 6 and 9?

Which is the LCM of 6, 7 and 9?
Because 126 is the first number to appear on both lists of multiples, 126 is the LCM of 6, 7 and 9. Quote of the day “What we learn with pleasure we never forget.”
Which is the smallest multiple of 6 and 8?
The LCM of 6 and 8 is 24 because 24 is the smallest number that is both a multiple of 6 and a multiple of 8. This calculator uses the listing multiples method. This method consisits of writing out a list of the lowest multiples of each number, and look for the lowest multiple both numbers have in common.
