## Q. What is the smallest number of 6 and 15?

30

FAQs on LCM of 6 and 15 The LCM of 6 and 15 is 30. To find the least common multiple (LCM) of 6 and 15, we need to find the multiples of 6 and 15 (multiples of 6 = 6, 12, 18, 24 . . . . 30; multiples of 15 = 15, 30, 45, 60) and choose the smallest multiple that is exactly divisible by 6 and 15, i.e., 30.

## Q. How to get the least common multiple of 6 and 18?

To get the Least Common Multiple (LCM) of 6 and 18 we need to factor each value first and then we choose all the factors which appear in any column and multiply them: The Least Common Multiple (LCM) is: 2 x 3 x 3 = 18 You can always share this solution

## Q. Which is the least common multiple in math?

Calculator Use. The Least Common Multiple ( LCM) is also referred to as the Lowest Common Multiple ( LCM) and Least Common Denominator ( LCD). For two integers a and b, denoted LCM( a,b ), the LCM is the smallest integer that is evenly divisible by both a and b. For example, LCM (2,3) = 6 and LCM (6,10) = 30.

## Q. How to calculate the LCM of 6, 18?

First we will calculate the prime factors of 6 and 18. Prime factors of 6 are 2, 3. Prime factorization of 6 in exponential form is: Prime factors of 18 are 2, 3. Prime factorization of 18 in exponential form is: Now multiplying the highest exponent prime factors to calculate the LCM of 6 and 18.

## Q. How to find the LCM using the greatest common factor?

The formula to find the LCM using the Greatest Common Factor GCF of a set of numbers is: A factor is a number that results when you can evenly divide one number by another. In this sense, a factor is also known as a divisor. The greatest common factor of two or more numbers is the largest number shared by all the factors.

In this video, I use a factor tree to find the least common multiple of 15 and 20The factor tree is an easy method for finding the prime numbers of a number.
