Question

HCF of 2 numbers is 5 and their LCM is 180 .if one of the two number is 45 fund the other number

Answer 1

Answer:

20

Step-by-step explanation:

HCF * LCM = Product of two numbers

5 * 180 = 45 * x

900 = 45x

x = 900/45

x = 20

The other number is 20

Answer 2

As we know

LCM × HCF = Product of two numbers

LCM = 180

HCF = 5

one number = 45

let other number be y

therefore,

180 × 5 = 45 × y

900 = 45 × y

900/45 = y

y = 20

other number is 20
