1, 3, 5, 15, 25, 75, 125, 375
The common multiples of 3 and 15 in the numbers 1-100: 15, 30, 45, 60, 75, 90
75: 1 + 75 + 3 + 25 + 5 + 15 = 124
1, 3, 5, 15, 25, 75: 1 x 75, 3 x 25, 5 x 15
1, 3 is next.* * * * *That is the least common factor (which is a meaningless concept), not the least common multiple!LCM(15, 45, 75) = 225
The factors of 75 are: 1, 3, 5, 15, 25, 75
15, 30, 45, 60, 75, 90... Because 15 is a multiple of 3, every multiple of 15 is a common multiple of 3.
The Least Common Multiple (LCM) for 3 5 75 is 75.
15 is a multiple of 1, a multiple of 3, a multiple of 5 and a multiple of 15. 1 x 15 = 15. 3 x 5 = 15.
The answer is 3.
The factors of 15 are 1, 3, 5, and 15 .The factors of 75 are 1, 3, 5, 15, 25, and 75 .The common factors ... numbers that are factorsof both 15 and 75 ... are 1, 3, 5, and 15 .
