The multiples of 20 are: 20, 40, 60, 80, 100, 120, 140, etc ...The multiples of 30 are: 30, 60, 90, 120, 150, etc ...The multiples of 40 are: 40, 80, 120, 160, etc. ...The lowest multiple common to 20, 30, and 40 is 120, so the LCM = 120
The least common multiple of 30 and 40 is found out by finding the prime factorizations of the 2 numbers 30 and 40, then to multiply the factors by the ones in unison and those not in unison. Therefore, the answer is 120120
LCM(2, 24, 30, 40) = 120.
The LCM is: 120
It's 10 i think...a lol
