## How-to: What is the LCM of 35, 60 and 75?

The below solved example with step by step work shows how to find what is the lcm of 35, 60 and 75 by using either prime factors method and special division method.

Solved example using prime factors method:
What is the LCM of 35, 60 and 75?

step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 35
B = 60
C = 75

What to be found:
find the lcm of 35, 60 and 75

step 2 Find the prime factors of 35, 60 and 75:
Prime factors of 35 = 5 x 7
Prime factors of 60 = 2 x 2 x 3 x 5
Prime factors of 75 = 3 x 5 x 5

step 3 Identify the repeated and non-repeated prime factors of 35, 60 and 75:
{3, 5} are the most repeated factors and {7, 2, 2, 5} are the non-repeated factors of 35, 60 and 75.

step 4 Find the product of repeated and non-repeated prime factors of 35, 60 and 75:
= 3 x 5 x 7 x 2 x 2 x 5
= 2100
lcm(20 and 30) = 2100

Hence,
lcm of 35, 60 and 75 is 2100

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 35, 60 and 75.

step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 35, 60 and 75

What to be found:
lcm (35, 60, 75) = ?

step 2 Arrange the given integers in the horizontal form with space or comma separated format:
35, 60 and 75

step 3 Choose the divisor which divides each or most of the given integers (35, 60 and 75), 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 35, 60 and 75 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

 2 35 60 75 2 35 30 75 3 35 15 75 5 35 5 25 5 7 1 5 7 7 1 1 1 1 1

step 4 Multiply the divisors to find the lcm of 35, 60 and 75:
= 2 x 2 x 3 x 5 x 5 x 7
= 2100
LCM(35, 60, 75) = 2100

The least common multiple for three numbers 35, 60 and 75 is 2100
