Question

find LCM of 16 and 28 and 40 by division method​

Answer 1

Step-by-step explanation:

The least common multiple 560 is a product of common & odd prime factors between the integers which is divisible by each one an integer of this same group.

Answer 2

Step-by-step explanation:

Problem & Workout :

step 1 Address input parameters & values.

Integers: 16 28 40

lcm (16, 28, 40) = ?

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

16, 28 and 40

step 3 Choose the divisor which divides each or most of the integers of in the group (16, 28 and 40), 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, 28 and 40

4 16 28 40

2 4 7 10

7 2 7 5

5 2 1 5

2 2 1 1

1 1 1

step 4 Multiply the divisors to find the lcm of 16, 28 and 40

4 x 2 x 7 x 5 x 2 = 560

LCM(16, 28, 40) = 560

The least common multiple for three numbers 16, 28 and 40 is 560
