Question

if the lcm and hcf of two numbers are 72 and 12 respectively find the second number if one number is 36​

Answer 1

Given -

• HCF of two numbers = 12
• LCM of numbers = 72
• One of the numbers = 36

To Find :-

• Other number - x ( let )

Solution -

We know that,

HCF × LCM = Product of two numbers

Substituting the value in formula -

➩ 72 × 12 = 36 × x

➩ 36x = 864

➩ x = 864/36

➩ x = 24

Required number = 24
