Download Solution PDFGiven:
HCF of two numbers = 4
LCM of two numbers = 80
One of the numbers is 4 more than the other
Formula used:
Product of two numbers = HCF × LCM
Calculation:
Let the smaller number be 4k
Then, the larger number = (4k + 4)
Now, the Product of two numbers = HCF × LCM
⇒ 4k(4k + 4) = 4 × 80
⇒ k(k + 1) = 20
k = 4 and it satisfy the equation.
Smaller number = 4k
⇒ 4(4) ⇒ 16
∴ The answer is 16.
