Question

The product of two numbers is 810 and there lCM is 90 Find Their HCF​

Answer 1

Answer:9

Step-by-step explanation:

LCM (x , y) * HCF ( x, y) = x * y[Here x and y are the two numbers]

90 * HCF = 810

HCF = 810/90

HCF = 9

Answer 2

Answer:

Hence, HCF is 9

Step-by-step explanation:

Product of two numbers is 810

LCM of two numbers is 90

HCF = ???

we know that,

HCF × LCM of two numbers = product of two no.

so,

90 × x = 810

90x = 810

x = 810/90

x = 9

Hence, HCF is 9
