We found the divisors of 65, 241, 782, 430 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 65, 241, 782, 430 is 1.

Therefore, GCD of numbers 65, 241, 782, 430 is 1

Given Input Data is 65, 241, 782, 430

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

Prime Factorization of 65 is 5 x 13

Prime Factorization of 241 is 241

Prime Factorization of 782 is 2 x 17 x 23

Prime Factorization of 430 is 2 x 5 x 43

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(65, 241) = 15665

GCD(65, 241) = ( 65 x 241 ) / 15665

GCD(65, 241) = 15665 / 15665

GCD(65, 241) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 782

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

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

GCD(1, 782) = 782 / 782

GCD(1, 782) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 430

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

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

GCD(1, 430) = 430 / 430

GCD(1, 430) = 1

GCD of 65, 241, 782, 430 is 1
