Therefore, GCD of numbers 34, 561, 619, 430 is 1

Given Input Data is 34, 561, 619, 430

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

Prime Factorization of 34 is 2 x 17

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 619 is 619

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(34, 561) = 1122

GCD(34, 561) = ( 34 x 561 ) / 1122

GCD(34, 561) = 19074 / 1122

GCD(34, 561) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 619

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

LCM(17, 619) = 10523

GCD(17, 619) = ( 17 x 619 ) / 10523

GCD(17, 619) = 10523 / 10523

GCD(17, 619) = 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 34, 561, 619, 430 is 1
