Answer 1

Hi ,

___________________________________
Coprime :

Two numbers are said to be coprime if

the only positive integer that divides both of

them is 1.

Or

If HCF of two positive numbers is 1 they are

called coprime.
___________________________________

According to the given problem,

If a and b are two pisitive numbers

a = 29 , b = ?

LCM = 638

HCF = 1 [ since a and b are coprime ]

We know that ,

a × b = HCF × LCM

b = ( HCF × LCM ) / a

b = ( 1 × 638 ) / 29

b = 22

Therefore ,

Required second number = b = 22

I hope this helps you.
