So the Greatest Common Divisior 53, 49, 78 is 1.

Therefore, GCD of numbers 53, 49, 78 is 1

Given Input Data is 53, 49, 78

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 53 is 53

Prime Factorization of 49 is 7 x 7

Prime Factorization of 78 is 2 x 3 x 13

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(53, 49) = 2597

GCD(53, 49) = ( 53 x 49 ) / 2597

GCD(53, 49) = 2597 / 2597

GCD(53, 49) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 78

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

GCD(1, 78) = 78 / 78

GCD(1, 78) = 1

GCD of 53, 49, 78 is 1
