Question

find the LCM of 32, 36 and 40 with prime factorisation?

Answer 1

Step-by-step explanation:

Address input values.

Integers: 32 36 40

lcm (32, 36, 40) = ?

step 2

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

32, 36 and 40

step 3

Choose the divisor which divides each or most of the integers of in the group (32, 36 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 32, 36 and 40

4 32 36 40

2 8 9 10

9 4 9 5

5 4 1 5

4 4 1 1

1 1 1

step 4

Multiply the divisors to find the lcm of 32, 36 and 40

4 x 2 x 9 x 5 x 4 = 1440

LCM(32, 36, 40) = 1440

The least common multiple for three numbers 32, 36 and 40 is 1440
