Question

if lcm of two numbers is 36 and hcf is 2 and one of the number is 18,find other numbrt

Answer 1

product of two numbers=LCM× HCF
18× x = 36× 2
where x is the another number
now
x= 36×2/18
x=4
here is your answer...
hope this helps you

Answer 2

Fact : HCF * LCM = Product of two numbers

Let the two numbers be ' a ' and ' b '.

Given that, HCF = 2, LCM = 36, ' a ' = 18.

To find, ' b ' = ?

Solution : Substituting in the formula we get,

2 * 36 = 18 * b

=> 72 = 18 * b

=> b = 72 / 18

=> b = 4

Hence the other number is 4.

Hence the two numbers are 2 and 4.

Hence solved !
