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.
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.
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.
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...
