Lowest common Multiplier of 16 and 84
16/2 = 9
8/2 = 4
4 /2 = 2
2/2 = 1
The Lowest common Multiplier is 2 x 2 x 2 x 2
2 factor out four times
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
84/2 = 42
42/2 = 21
21/3 = 7
7/7 = 1
The Lowest Common Multiplier for 84 is 2 x 2 x 3 x 7
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Since 2 factors out four times from 16
2 x 2 x 2 x 2
Since 84 Factor out 2 x 2 x 3 x 7
The Lowest common Multiplier is
2 x 2 x 2 x 2 x 3 x 7 = 336
The answer is 336
