step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 191 and 192
What to be found:
lcm (191, 192) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
191 and 192
step 3 Choose the divisor which divides each or most of the given integers (191 and 192), 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 191 and 192 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 191 | 192 |
| 2 | 191 | 96 |
