Question

Find the LCM of 70, 80, 90 by common division method.​

Answer 1

The least common multiple for three numbers 70, 80 and 90 is 5040

Step-by-step explanation:

step 1 Address input parameters & values.

Integers: 70 80 90

LCM (70, 80, 90) = ?

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

70, 80 and 90

step 3 Choose the divisor which divides each or most of the integers of in the group (70, 80 and 90), 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 70, 80 and 90

10 70 80 90

7 7 8 9

8 1 8 9

9 1 1 9

1 1 1

step 4 Multiply the divisors to find the LCM of 70, 80 and 90

10 x 7 x 8 x 9 = 5040

LCM(70, 80, 90) = 5040

The least common multiple for three numbers 70, 80 and 90 is 5040
