1. 70
2. 140
3. 280
4. 200

Answer 1

Correct Answer - Option 1 : 70

Given:

The H.C.F and L.C.M of two numbers are 14 and 140 respectively

and one of these numbers is 28.

Formula used:

Product of two numbers = (L.C.M × H.C.F)

Calculation:

Let the other number be x.

According to the question,

Product of two numbers = (L.C.M × H.C.F)

⇒ 28 × x = 140 × 14

⇒ 28x = 1960

⇒ x = 70

∴ The other number will be 70.
