### Which is the least common multiple?

In arithmetic and number theory, the least common multiple, lowest common multiple, or smallest common multiple of two integers a and b, usually denoted by lcm(a, b), is the smallest positive integer that is divisible by both a and b.

**How do you find the least common multiple of 2?**

Find the least common multiple (LCM) of two numbers by listing multiples

- List the first several multiples of each number.
- Look for multiples common to both lists.
- Look for the smallest number that is common to both lists.
- This number is the LCM.

**What is the least common multiple of 2 4 and 8?**

8

Answer: LCM of 2, 4, and 8 is 8.

#### What is a common multiple of 2 and 3?

The LCM of 2 and 3 is 6. To find the LCM (least common multiple) of 2 and 3, we need to find the multiples of 2 and 3 (multiples of 2 = 2, 4, 6, 8; multiples of 3 = 3, 6, 9, 12) and choose the smallest multiple that is exactly divisible by 2 and 3, i.e., 6.

**What is the difference between LCM and a common multiple?**

A common multiple is a number which is a multiple of two or more numbers. LCM denotes the least common factor or multiple of any two or more given integers. For example, L.C.M of 16 and 20 will be 2 x 2 x 2 x 2 x 5 = 80, where 80 is the smallest common multiple for numbers 16 and 20.

**What is the least common multiple of two numbers?**

In mathematics, the least common multiple, also known as the lowest common multiple of two (or more) integers a and b, is the smallest positive integer that is divisible by both. It is commonly denoted as LCM (a, b).

## What is the least common multiple of 16 and 20?

LCM denotes the least common factor or multiple of any two or more given integers. For example, L.C.M of 16 and 20 will be 2 x 2 x 2 x 2 x 5 = 80, where 80 is the smallest common multiple for numbers 16 and 20. 16 → 16, 32, 48, 64, 80,…

**What is the LCM of the given expressions?**

The LCM is made by multiplying all factors included in the factoring of the given expressions. Common factors are used once only and the one with the highest power is used. 2 is a factor in the first expressions is therefore used. x + 1 is a factor in the first and second expressions is used once only.
