How to get the lcm in math

Sagot :

LCM is the Least Common Multiple of 2 or more numbers.
Example:
  1) LCM of 3 and 5
    Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
    Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50
  Since 15 is the least common multiple of 3 and 5, the LCM of 3 and 5 is 15.
  2) LCM of 2, 3 and 5
    Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30
    Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
    Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50
  Since 30 is the least common multiple of 2, 3 and 5, the LCM of 2, 3 and 5 is 30.
