Question

two numbers are coprime and their LCM is 4940 if one of the numbers is 65 find the other number

Answer 1

Let another number be X
So,
65X =4940
X =76
Hence another number is 76

Answer 2

ANSWER:  

Two numbers are co-prime and their LCM is 4940. Then the other number is 76

SOLUTION:

Given, two numbers are co-prime  

And their LCM is 4940

One of the numbers is 65

We need to find the other number.

Let the other number be x.

Now, we know that H.C.F of co primes = 1

And we also know that, H.C.F x L.C.M = product of two numbers.

Now, 1 x 4940 = 65 × x

65x = 4940

$x=\frac{4940}{65}=76$

Hence, the other number is 76.
