Question

The LCM of two numbers is 2310 and their HCF is 30. If one of these numbers is 210, find the second number?

Answer 1

Answer:

330

Step-by-step explanation:

product of two numbers is equal to lcm×hcf

implies

Lcm×Hcf/givenno.= unknown no.

which is equal to

(2310×30)/210=330

Answer 2

The Second Number is 330.

Step-by-step explanation:

Given :

LCM of the two numbers = 2310

HCF = 30

One Number = 210

To Find :

Second Number

Solution :

Consider the Second Number as y

We know that -

★ HCF × LCM = Product of two numbers

➠ 30 × 2310 = 210 × y

➠ 69300 = 210y

➠ y = 69300/210

➠ y = 330

∴ The Second Number is 330.
