Question

The LCM and HCF of two positive numbers are 300 and 30 respectively. If one number is divided by 4, the quotient is 15, then what is the other number? Select one:

Answer 1

According to given information

LCM = 300

HCF = 30

Let one number is 'x' and the other number is 'y'. so

x /4 = 15

x = 15 (4) = 60

Now

LCM × HCF = Product of the Numbers

300 × 30    =   x y

9000 = 60 y  ⇒  y = 9000/60 = 150

One number is 60 and the other number is 150.
