Question

Product of 2 numbers is 210 and their HCF is 1. What is their LCM ?

Answer 1

it is 210 . sa there is a formula
LCM = PRODUCT /SUM

Answer 2

Concept:

The Product of the HCF and LCM of the two numbers is equal to the product of the two numbers.

Given:

The product of the two numbers is 210 and the HCF of the two numbers is 1.

Find:

The LCM of the given two numbers.

Solution:

Let, the LCM of the two numbers be x.

As we know that the Product of the HCF and LCM of the two numbers is equal to the product of the two numbers.

1 × x = 210

x = 210/1

x = 210

Hence, the LCM of the two given numbers is 210, whose HCF is 1, and the product of the two numbers is 210.
