## How to find LCM(3, 5, 7, 9, 2, 1)?

Follow the below steps to find the least common multiple of given group of integers or whole numbers 3, 5, 7, 9, 2 and 1 by using the most efficient and easiest method.

**:**

__Problem & Workout__step 1 Address input parameters & values.

Integers: 3 5 7 9 2 1

lcm (3, 5, 7, 9, 2, 1) = ?

step 2 Arrange the group of numbers in the horizontal form with space or comma separated format

3, 5, 7, 9, 2 and 1

step 3 Choose the divisor which divides each or most of the integers of in the group (3, 5, 7, 9, 2 and 1), divide each integers separately and write down the quotient in the next line right under the respective integers. Bring down the integer to the next line if the integer is not divisible by the divisor. Repeat the same process until all the integers are brought to 1.
