step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 13
B = 27
C = 50
What to be found:
Find lcm of 13, 27 and 50
step 2 Find the prime factors of 13, 27 and 50:
Prime factors of 13 = 13
Prime factors of 27 = 3 x 3 x 3
Prime factors of 50 = 2 x 5 x 5
step 3Identify the repeated and non-repeated prime factors of 13, 27 and 50:

13, 27 and 50.
= 13 x 27 x 50
= 17550
LCM(13, 27 and 50) = 17550
Hence,
The Least Common Multiple of 13, 27 and 50 is 17550
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 13, 27 and 50.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 13, 27 and 50
What to be found:
lcm (13, 27, 50) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
13, 27 and 50
step 3 Choose the divisor which divides each or most of the given integers (13, 27 and 50), 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 13, 27 and 50 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 13 | 27 | 50 |
| 3 | 13 | 27 | 25 |
| 3 | 13 | 9 | 25 |
| 3 | 13 | 3 | 25 |
| 5 | 13 | 1 | 25 |
