Question

Lcm of 7 10 and 3. What is the lcm of 15, 3, and 2. What is the lsm of 7,3,5. Lcm of 4 and 7.

Answer 1

Answer: 28

Explanation:

Answer 2

1. LCM of 7, 10 and 3 = 210

2. LCM of 15, 3 and 2 = 30

3. LCM of 7, 3 and 5 = 105

4. LCM of 4 and 7 = 28

Explanation:

Solving (1): LCM of 7, 10 and 3

First, factorize each of the numbers:

`7 = 1 * 7`

`10 = 1 * 2 * 5`

`3 = 1 * 3`

Multiply the factors the highest number of times it occur in any of the terms

`LCM = 1 * 2 * 3 * 5 * 7`

`LCM = 210`

Solving (2): LCM of 15, 3 and 2

First, factorize each of the numbers:

`15 =1 * 3 * 5`

`3 = 1 * 3`

`2 = 1 * 2`

Multiply the factors the highest number of times it occur in any of the terms

`LCM = 1 * 2 * 3 * 5`

`LCM = 30`

Solving (3): LCM of 7, 3 and 5

First, factorize each of the numbers:

`7 = 1 * 7`

`3 = 1 * 3`

`5 = 1 * 5`

Multiply the factors the highest number of times it occur in any of the terms

`LCM = 1 * 3 * 5 * 7`

`LCM = 105`

Solving (4): LCM of 4 and 7

First, factorize each of the numbers:

`4 = 1 * 4`

`7 = 1 * 7`

Multiply the factors the highest number of times it occur in any of the terms

`LCM = 1 * 4 * 7`

`LCM = 28`
