HCF of two numbers 36 and 90 is 18. Find the LC


The relationship between the Highest Common Factor (HCF) and the Least Common Multiple (LCM) of two numbers is given by the formula:

\[
\text{HCF} \times \text{LCM} = \text{Product of the two numbers}
\]

In this case, the numbers are 36 and 90, and the HCF is 18. Let \( \text{LCM} \) be \( x \).

\[
18 \times x = 36 \times 90
\]

First, calculate the product of 36 and 90:

\[
36 \times 90 = 3240
\]

Now, solve for \( x \):

\[
x = \frac{3240}{18} = 180
\]

Thus, the Least Common Multiple (LCM) of 36 and 90 is **180**.
