We found the divisors of 19, 260, 649, 260 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 19, 260, 649, 260 is 1.

Therefore, GCD of numbers 19, 260, 649, 260 is 1

Given Input Data is 19, 260, 649, 260

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

Prime Factorization of 19 is 19

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 649 is 11 x 59

Prime Factorization of 260 is 2 x 2 x 5 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(19, 260) = 4940

GCD(19, 260) = ( 19 x 260 ) / 4940

GCD(19, 260) = 4940 / 4940

GCD(19, 260) = 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 260

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

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

GCD(1, 260) = 260 / 260

GCD(1, 260) = 1

GCD of 19, 260, 649, 260 is 1
