Answer 1

336 is the LCM for above group of non-negative integers and is divisible by each integers of this group.

Problem & Workout :

step 1 Address input parameters & values.

16 21 24

lcm (16, 21, 24) = ?

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

16, 21 and 24

step 3 Choose the divisor which divides each or most of the integers of in the group (16, 21 and 24), 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.

LCM of 16, 21 and 24

16 21 24

2 21 3

2 7 1

1 7 1

1 1

step 4 Multiply the divisors to find the lcm of 16, 21 and 24

8 x 3 x 2 x 7 = 336

lcm (16, 21, 24) = 336

336 is least common multiple for three numbers 16, 21 and 2
