What is the least common multiple of 5 18 and 24?

Answer 1

120 is the least common multiple.

24*1=24

24*2=48

24*3=72

24*4=96

24*5=120

5*1=5

5*2=10

...

5*60=120
Because 5 and 24 do not share a common prime factor then the LCM is the product of the two. 5*24=120

Answer 2

The first step in finding the least common multiple of 3 numbers is to break those numbers down into their prime factors. In this case:

5=5

24=2x2x2x3

6=2x3

The next step is to identify any common prime factors. In this case, two numbers have a 2 and a 3 as prime factors, so we can discard one of each. That leaves us with 5, 2, 2, 2 and 3. Multiply these together to get the LCM:

5x2x2x2x3 = 120

Thus the least common multiple of 5, 24 and 6 is 120.
