Question

The Lcm of two number is (a+b) and their HCF P(a-b).If one of the number is P, then another number is​

Answer 1

Answer:

a^2 - b^2

Step-by-step explanation:

given that for two numbers

HCF= r(a−b)

 

LCM=a+b

one number is r

using the formula 

HCF×LCM=n×m

where n,m are two numbers 

Now 

r(a−b)×(a+b)=r×m

(a−b)×(a+b)=m

⇒m=a2−b2

The other number is   a2−b2
