## How to calculate the LCM of a set of numbers?

The LCM is the product of the prime numbers in the first column. 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.

**Which is the least common multiple in this calculator?**

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

**Which is the least common multiple of 6 7 21?**

Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60. Multiples of 7: 7, 14, 21, 28, 35, 42, 56, 63. Multiples of 21: 21, 42, 63. Find the smallest number that is on all of the lists. We have it in bold above. So LCM (6, 7, 21) is 42.

### How to calculate the HCF of 63 and 9?

Step 1: Since 63 > 9, we apply the division lemma to 63 and 9, to get. 63 = 9 x 7 + 0. The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 9 and 63 is 9. Notice that 9 = HCF(63,9) .
