Therefore, GCD of numbers 619, 998, 61, 457 is 1

Given Input Data is 619, 998, 61, 457

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

Prime Factorization of 619 is 619

Prime Factorization of 998 is 2 x 499

Prime Factorization of 61 is 61

Prime Factorization of 457 is 457

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(619, 998) = 617762

GCD(619, 998) = ( 619 x 998 ) / 617762

GCD(619, 998) = 617762 / 617762

GCD(619, 998) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 457

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

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

GCD(1, 457) = 457 / 457

GCD(1, 457) = 1

GCD of 619, 998, 61, 457 is 1
