Question

Do as directed. 1) Find the LCM. 30,60,90.

​

Answer 1

Answer:

LCM(30, 60 and 90) = 180

Step-by-step explanation:

step 1 Address input parameters & values.

Integers: 30 60 90

lcm (30, 60, 90) = ?

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

30, 60 and 90

step 3 Choose the divisor which divides each or most of the integers of in the group (30, 60 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 30, 60 and 90

30 30 60 90

2 1 2 3

3 1 1 3

1 1 1

step 4 Multiply the divisors to find the lcm of 30, 60 and 90

30 x 2 x 3 = 180

LCM(30, 60, 90) = 180

The least common multiple for three numbers 30, 60 and 90 is 180
