$54$

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 $27 \times 2 = 54$

$\Rightarrow \frac{54}{18} = 3 \leftarrow \text{ divides exactly}$

$\text{ Hence 54 is the LCM of 27 and 18}$
