30, 60, 90.
Since 3 is a factor of 15, the first three common multiples of 3 and 15 are 15, 30, and 45.
15, 30, 45
15 & 20 have an infinite number of Common Multiples; the first three are 60, 120 and 180.
15, 30, and 45 are.
5 10 15 20 25 30
LCM=Least common multiple Thus,the least number that multiplies both 15 and 25 is %. sorry about the GCF ?
60, 120 and 180
