We found the divisors of 515, 786, 139, 686 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 515, 786, 139, 686 is 1.

Therefore, GCD of numbers 515, 786, 139, 686 is 1

Given Input Data is 515, 786, 139, 686

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

Prime Factorization of 515 is 5 x 103

Prime Factorization of 786 is 2 x 3 x 131

Prime Factorization of 139 is 139

Prime Factorization of 686 is 2 x 7 x 7 x 7

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(515, 786) = 404790

GCD(515, 786) = ( 515 x 786 ) / 404790

GCD(515, 786) = 404790 / 404790

GCD(515, 786) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 139

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

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

GCD(1, 139) = 139 / 139

GCD(1, 139) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 686

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

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

GCD(1, 686) = 686 / 686

GCD(1, 686) = 1

GCD of 515, 786, 139, 686 is 1
