LCM = 20 × HCF (given)
Let HCF = x
LCM = 20x ( according to given condition)
LCM + HCF = 2520
20x + x = 2520
21x = 2520
x = 2520 / 21
x = 120
The HCF is 120
The LCM is 2400
One number is 480
Other nunber is y
The product if the two number is = HCF × LCM
480 × y = 120 × 2400
y = 120 × 2400/480
y = 600
The other number is 600.
