step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 14
B = 27
C = 65
What to be found:
Find lcm of 14, 27 and 65
step 2 Find the prime factors of 14, 27 and 65:
Prime factors of 14 = 2 x 7
Prime factors of 27 = 3 x 3 x 3
Prime factors of 65 = 5 x 13
step 3Identify the repeated and non-repeated prime factors of 14, 27 and 65:
Since there is no common factors between 14, 27 and 65, multiplying the given numbers directly provides the LCM of
14, 27 and 65.
= 14 x 27 x 65
= 24570
LCM(14, 27 and 65) = 24570
Hence,
The Least Common Multiple of 14, 27 and 65 is 24570
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 14, 27 and 65.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 14, 27 and 65
What to be found:
lcm (14, 27, 65) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
14, 27 and 65
step 3 Choose the divisor which divides each or most of the given integers (14, 27 and 65), 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 14, 27 and 65 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 14 | 27 | 65 |
| 3 | 7 | 27 | 65 |
| 3 | 7 | 9 | 65 |
| 3 | 7 | 3 | 65 |
