This special division method is the easiest way to understand the entire calculation of what is the lcm of 100 and 118.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 100 and 118
What to be found:
lcm (100, 118) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
100 and 118
step 3 Choose the divisor which divides each or most of the given integers (100 and 118), 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 100 and 118 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 100 | 118 |
| 2 | 50 | 59 |
