Question

How do you find the Least common multiple of 27, 18?

Answer 1

`54`

Explanation:

One way of finding the lowest common multiple ( LCM ) is.

`•" Divide the larger number by the smaller number"`

`•" If it divides exactly then larger number is LCM"`

`•" If not then repeat with multiples of larger number"`

`rArr27÷18" or " 27/18larr" does not divide exactly"`

Now we try `27xx2=54`

`rArr54/18=3larr" divides exactly"`

`" Hence 54 is the LCM of 27 and 18"`
