Question

The HCF of two numbers is 145 and their LCM is 2175. If one of the numbers is 725, find the other.

Answer 1

HCF of two numbers = 145

LCM of two numbers = 2175

Let one of the two numbers be 725 and other be x.

Using the formula, product of two numbers = HCF × LCM

We conclude that

725 × x = 145 × 2175

x = `(145 xx 2175)/725`

= 435

Hence, the other number is 435.
