Question

The HCF of two numbers is 40 and LCM is 60. If one of the numbers is 30, find the other number. Is this a valid question?​

Answer 1

Answer:

80

Step-by-step explanation:

LCM x HCF = product of two no.

40 × 60 = 30 × x

x = 80

Answer 2

Answer:

80

Step-by-step explanation:

Suppose the other no. is s

HCF= 40

LCM=60

LCM×HCF=Product of two no.

40*60=30*s

2400=30s

s=2400/30

s=80

So, other number is 80
