60, 120, 180 and so on.
Any multiples of 20.
Ans: 15, 30 and 45 Prime factorization of 3 and 15 3: 3 15: 3 x 5 15, 30 and 45. Hi My names Bob
the common multiples of 20 and 25 is 100 (through 100)
To find the common multiples of 2, 5, and 9, we first list the multiples of each number. The multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, ... The multiples of 5 are 5, 10, 15, 20, 25, 30, ... The multiples of 9 are 9, 18, 27, 36, ... The common multiples of 2, 5, and 9 are the numbers that appear in all three lists, which are the multiples of the least common multiple (LCM) of 2, 5, and 9. The LCM of 2, 5, and 9 is 90, so the common multiples are 90, 180, 270, ...
15 & 20 have an infinite number of Common Multiples; the first three are 60, 120 and 180.
The common multiples of 9, 15, and 20 are an infinite set of multiples of their least common multiple, which is 180. so the common multiples of 9, 15, and 20 are 180, 360, 540, 720, 900, 1080, 1260, 1440, 1620, 1800, and so on.
60 and all its multiples
The multiples of 20 are 20, 40, 60, 80, 100, 120... The multiples of 30 are 30, 60, 90, 120, 150... The multiples of 15 are 15, 30, 45, 60, 75, 90, 105, 120, 135... The common multiples of 20, 30, and 15 are 60, 120, 180, 240...
LCD= 60
Multiples of 5 include 5, 10, 15 and 20. For them to be common, they need to be compared to another set of multiples.
The LCM is 60
The common multiples of 4 and 5 are 20, 40, 60, 80,100 and so onGet the least common multiple of the two. All other common multiples are multiples of this least common multiple.Any multiple of 20.
The Least Common Multiple (LCM) for 10 15 20 is 60.
The two smallest multiples of 10 are 10 and 20. For them to be common, they would need to be compared to another set of multiples.
They are both multiples of 5
10 and 15 15 and 20 20 and 25
