step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 63, 82 and 95
What to be found:
lcm (63, 82, 95) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
63, 82 and 95
step 3 Choose the divisor which divides each or most of the given integers (63, 82 and 95), 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 63, 82 and 95 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 63 | 82 | 95 |
