What is the LCM of 35, 55 and 100?

step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 35
B = 55
C = 100

What to be found:
find the lcm of 35, 55 and 100

step 2 Find the prime factors of 35, 55 and 100:
Prime factors of 35 = 5 x 7
Prime factors of 55 = 5 x 11
Prime factors of 100 = 2 x 2 x 5 x 5

lcm of 35, 55 and 100 is 7700

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, 55 and 100.

step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 35, 55 and 100

What to be found:
lcm (35, 55, 100) = ?

step 2 Arrange the given integers in the horizontal form with space or comma separated format:
35, 55 and 100

step 3 Choose the divisor which divides each or most of the given integers (35, 55 and 100), 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, 55 and 100 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

 2 35 55 100 2 35 55 50 5 35 55 25 5 7 11 5 7 7 11 1 11 1 11 1 1 1 1
