Question

The HCF of two numbers is 0.05 and the product of the numbers is 0.825. What is the LCM of the numbers?

• A. 16.5
• B. 165
• C. 0.55
• D. 1.6

Answer 1

The correct option is A

16.5

For any two numbers a and b, $a\times b$ = LCM of a and b $\times$ HCF of a and b
Given, HCF of two numbers = 0.05
Product of the numbers = 0.825

$\Rightarrow$ 0.825 = LCM x 0.05
$\Rightarrow LCM=\frac{0.825}{0.05}$
$\Rightarrow LCM=16.5$
