10, (lowest number that is divisible by 2 and 5).
The Least Common Multiple (LCM) for 2 3 5 is 30.
Both 2 and 5 are prime numbers so their product 2 x 5 = 10 is the Lowest (or Least) Common Multiple. The common multiples of 2 and 5 are therefore any number which is a multiple of 10.
30
The lowest common multiple is 60.
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
Use the methods you learned to get the least common multiple. Then multiply this result by 2, and by 3, to get the next multiples.
The first 5 common multiples are the first 5 multiples of their lowest common multiple (LCM) LCM(9, 10) = 90 → first 5 common multiples are 90, 180, 270, 360, 450.
35 7x5
The LCM is: 25
The LCM is 30.
The Lowest Common Multiple (LCM) of 3 and 10 would be 30
Since the lowest common multiple of 3 and 5 is 15, the common multiples of 3 and 5 are the multiples of 15: 30, 45, 60, 75, 90, etc...
