What is LCM of 54, 62 and 88?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 54
B = 62
C = 88
What to be found:
Find lcm of 54, 62 and 88
step 2 Find the prime factors of 54, 62 and 88:
Prime factors of 54 = 2 x 3 x 3 x 3
Prime factors of 62 = 2 x 31
Prime factors of 88 = 2 x 2 x 2 x 11

= 2 x 3 x 3 x 3 x 31 x 2 x 2 x 11
= 73656
LCM(54, 62 and 88) = 73656
Hence,
The Least Common Multiple of 54, 62 and 88 is 73656
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 54, 62 and 88.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 54, 62 and 88
What to be found:
lcm (54, 62, 88) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
54, 62 and 88
step 3 Choose the divisor which divides each or most of the given integers (54, 62 and 88), 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 54, 62 and 88 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 54 | 62 | 88 |
