What is the LCM of 10 and 4?

Answer 1

Gianna Caruso

#LCM=20#

multiples of #10:{10,color(red)(20),30,40,50,...}#

multiples #4:{4,8,12,16,color(red)(20),24,28,32,36,40,...}#

common multiples#{20,40,....}#

Since 20 is the first shared value, LCM = 20.

The final digit will be 0 if you multiply 10 by any whole number. Therefore, we need to find the first multiple of 4 that will result in a zero as the final digit.

This is #4xx5=20#

Thus, LCM = 20
