Answer 1

step 1 Address input parameters & values.

Integers: 36 54 81

lcm (36, 54, 81) = ?

step 2 Arrange the group of numbers in the horizontal form with space or comma separated format

36, 54 and 81

step 3 Choose the divisor which divides each or most of the integers of in the group (36, 54 and 81), 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 the integer is not divisible by the divisor. Repeat the same process until all the integers are brought to 1.
