Therefore, GCD of numbers 263, 337, 649, 505 is 1

Given Input Data is 263, 337, 649, 505

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

Prime Factorization of 263 is 263

Prime Factorization of 337 is 337

Prime Factorization of 649 is 11 x 59

Prime Factorization of 505 is 5 x 101

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(263, 337) = 88631

GCD(263, 337) = ( 263 x 337 ) / 88631

GCD(263, 337) = 88631 / 88631

GCD(263, 337) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 649

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

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

GCD(1, 649) = 649 / 649

GCD(1, 649) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 505

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

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

GCD(1, 505) = 505 / 505

GCD(1, 505) = 1

GCD of 263, 337, 649, 505 is 1
