Question : 36 of 40

Marks: +1, -0

The HCF and LCM of two numbers is 12 and 360 respectively. Find the possible pair of such numbers.

Solution:

Let two numbers be 12x and 12y.

12x × 12y = 12 × 360

x × y = 30

So, possible pairs = (1, 30), (2, 15), (3, 10), (5, 6)
So, 4 such pairs of numbers are possible.
