Therefore, GCD of numbers 558, 438, 577, 563 is 1

Given Input Data is 558, 438, 577, 563

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

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 438 is 2 x 3 x 73

Prime Factorization of 577 is 577

Prime Factorization of 563 is 563

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(558, 438) = 40734

GCD(558, 438) = ( 558 x 438 ) / 40734

GCD(558, 438) = 244404 / 40734

GCD(558, 438) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 577

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

LCM(6, 577) = 3462

GCD(6, 577) = ( 6 x 577 ) / 3462

GCD(6, 577) = 3462 / 3462

GCD(6, 577) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 563

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

LCM(1, 563) = 563

GCD(1, 563) = ( 1 x 563 ) / 563

GCD(1, 563) = 563 / 563

GCD(1, 563) = 1

GCD of 558, 438, 577, 563 is 1
