Lcm of a Math Number Examples

Introduction for lcm of a math number examples:

The lowest common multiple (LCM) or least common multiple (LCM) of two rational numbers a and b is the smallest positive rational number that is an integer multiple of both a and b. Since it is a multiple, it can be divided by a and b without a remainder. If either a or b is 0, so that there is no such positive integer, then LCM(a, b) is defined to be zero.

Examples for Lcm of a Math Number Examples:

Example 1:

Find the lcm of a math number examples 3 and 9.

Solution:

Multiples of the given number,

3      : 3, 6, 9, 12, 15, 18,21,24,27,

9      : 9, 18, 27

Now we have to pick out lest common multiple of the both number examples 3 and 9. Therefore, The LCM of math number examples 3 and 9 is 9

Example 2:

Find the lcm of a math number examples 4 and 12.

Solution:

Multiples of the given number,

4     : 4, 8, 12, 16, 20, 24, 28, 32, 36

12   : 12, 24, 26

Now we have to pick out lest common multiple of the both number examples 4 and 12. Therefore, The LCM of math number examples 4 and 12 is 12

Example 3:

Find the LCM of a math number examples 5 and 6.

Solution:

Multiples of the given number,

5      :  5, 10, 15, 20, 25, 30, 35, 40, 45, 50

6      :  6, 12, 18, 24, 30, 36, 42, 48, 54, 60

Now we have to pick out lest common multiple of the both number examples 5 and 6. Therefore, The LCM of math number examples 5 and 6 is 30.Understanding how to find the variance is always challenging for me but thanks to all math help websites to help me out.
