The H.C.F. of two numbers is 18. First number is of three digits and S...

Let the numbers be 18x and 18y where x and y are co-prime.

LCM of 18x and 18y = 18xy

According to the question,

18xy = 936

⇒ xy = 936/18

⇒ xy = 52

⇒ xy = 13 × 4

⇒ x =13 and y = 4

First number = 18 × 13 = 234

Second number = 18 × 4 = 72

∴ Sum of both numbers = 234 + 72 = 306
