is

Step-by-step explanation:

Problem & Workout :

step 1 Address input parameters & values.

Integers: 10 15 20

lcm (10, 15, 20) = ?

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

10, 15 and 20

step 3 Choose the divisor which divides each or most of the integers of in the group (10, 15 and 20), divide each integers separately and write down the quotient in the next line right under the respective 60integers. 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.

LCM of 10, 15 and 20

5 10 15 20

2 2 3 4

3 1 3 2

2 1 1 2

1 1 1

step 4 Multiply the divisors to find the lcm of 10, 15 and 20

5 x 2 x 3 x 2 = 60

LCM(10, 15, 20) = 60

The least common multiple for three numbers 10, 15 and 20 is 60
