Answer 1

Given :

• product of two numbers = 8640
• their lcm = 360

To find :

• their hcf

Solution :

• We must know that, product of two numbers = product of their lcm and hcf

• Using the above formula and values given, we can write ---

• 360 × hcf = 8640
• or, hcf = 8640 ÷ 360
• or, hcf = 24

Answer :

• hcf of the given numbers is 24.
