# What is LCM of 3, 5, 7, 9, 2 and 1?

getcalc.com's LCM calculator and work with steps follows a special method to find what is Least Common Multiple for group of whole numbers or non-negative integers 3, 5, 7, 9, 2 and 1.

LCM(3, 5, 7, 9, 2 and 1) =

The least common multiple is a product of common and odd prime factors between the integers which is divisible by each one an integer of this same group. The step by step work for LCM of 3, 5, 7, 9, 2 and 1 may useful to understand how to find LCM for two or three numbers.

## How to find LCM(3, 5, 7, 9, 2 and 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.

__Solved example using special division method:__

This special division method is the easiest way to understand the entire calculation of what is the lcm of 3, 5, 7, 9, 2 and 1.

step 1 Address the input parameters, values and observe what to be found:

__Input parameters and values:__

Integers: 3, 5, 7, 9, 2 and 1

__What to be found:__

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

step 2 Arrange the given integers 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 given integers (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 any integer in 3, 5, 7, 9, 2 and 1 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

2 | 3 | 5 | 7 | 9 | 2 | 1 |

3 | 3 | 5 | 7 | 9 | 1 | 1 |

3 | 1 | 5 | 7 | 3 | 1 | 1 |

5 | 1 | 5 | 7 | 1 | 1 | 1 |

7 | 1 | 1 | 7 | 1 | 1 | 1 |

1 | 1 | 1 | 1 | 1 | 1 |

step 4 Multiply the divisors to find the lcm of 3, 5, 7, 9, 2 and 1:

= 2 x 3 x 3 x 5 x 7

= 630

LCM(3, 5, 7, 9, 2, 1) = 630

The least common multiple for 3, 5, 7, 9, 2 and 1 is 630
