15 and 5 both go into every multiple of 15 .
Exactly 15 times
what goes into both 21 and 25
Both 15 and 20 can go into 60, as they are both factors of that number.
25/15 = 1.6666... = 1 2/3 times
The LCM of 15 and 25 is 75
15 and 25 both go into 75. It's kind of obvious once you think about it ~Peace Out
