Least Common Multiple (LCM)

In the last section, we found that

GCF( 16 , 6 ) = 2
 

So, LCM( 16 , 6 ) = ( 16 x 6 / 2 ) = 48
 

Let's check this using multiple lists:

6 : 6 , 12 , 18 , 24 , 30 , 36 , 42 , ( 45 ) , ...
16 : 16 , 32 , ( 48 ) , ...

Yep!

In the last section, we found

GCF( 600 , 136 ) = 8
 

So, LCM( 600 , 136 ) = ( 600 x 136 / 8 ) = 10,200


No, I'm not geeky enough to want to check this with multiple lists! 

 

YOUR TURN:

Use this info you got in the last section to find

LCM( 100 , 6 )
 

LCM( 234 , 15 )
 

LCM( 12348 , 122 )
 

LCM( 9317, 125 )
 

The last one might be too big for your calculator to crunch!
