Question

The HCF of two numbers is 20. If the numbers are in the ratio 2:5, then their LCM IS:

Answer 1

Let ' x ' be the HCF of that two numbers and, the numbers be 2x and 5x

so,

HCF = 20

so, x = 20

then,

NUMBERS ARE 40,100

LCM = 40(100)/20 = 200

Answer 2

Hey

Here's the step by step explanation for your answer:

Given that,

The HCF of the numbers = 20

The numbers are in the ratio 2:5

So the numbers are-

2×20= 40

5×20= 100

So, the numbers are 40 and 100.

Therefore, the LCM of the numbers are 200.
