Answer 2

The (HCF x LCM) for the numbers 125 and 80 is 10000

First of all, we break the numbers 125 and 80 into their corresponding factors.

125 = 5*5*5

80 = 2*2*2*2*5

The highest common factor between 125 and 80 (HCF) is 5.

The least common multiple between 125 and 80 (LCM) is (2*2*2*2*5*5*5) = 2000

To find the required (HCF * LCM), we multiply 5 and 2000.

It is (5*2000)

= 10000
