What is the least common multiple of 2 3 4 and 5?

Answer 1

The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.

The least common multiple of 2, 3, 4, and 5 is 60.

Answer 2

60

its not 20 because it can't be divided by 3 equally. It can only end in a 0 because if it ends in a five it can't be divided by four. It cant be 30 because 4 does not go into it equally. 3 cant go into 40 equally and with 50 both 3 & 4 can't go into it equally. With 60 2 will go into it 30 times, 3 will go into it 20 times, 4 will go into it 15 times, and 5 will go into it 12 times.
