ben exercises every 12 days and isabella every 8 days. both isabella and ben exercised today. how many days till they exercise together again?

Answer 1

For them to exercise together again, the day must be a common multiplier of 12 and 8

12 =
`2^(2) . 3`
8 =
`2^(3)`

So, their LCM is
`2^(3) .3 = 24`

=> After 24 days, they will exercise together again.
