$18$ and $27$

Answer 1

Find first five common multiples of given number:

Multiple of a given number is a number obtained by multiplying it by an integer.

Taking the positive integers $\left(1,2,3,4,5....\right)$ and multiplying them with the given numbers, we can obtain the first five common multiples as:

The multiples of $18$ are:

$18,36,54,72,108,126,144,162,180,198,216,234,252,270,288,306,324$

The multiples of $27$ are:

$27,54,81,108,135,162,189,216,243,270,297,324,351,378,405...$

From the above multiples, we find the first five common multiples of $18$ and $27$ as $54,108,162,216$ and $270$.

Hence, $54,108,162,216$ and $270$ are the first five common multiples of $18$ and $27$.
