Given Input Data is 643, 991, 562, 883

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

Prime Factorization of 643 is 643

Prime Factorization of 991 is 991

Prime Factorization of 562 is 2 x 281

Prime Factorization of 883 is 883

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(643, 991) = 637213

GCD(643, 991) = ( 643 x 991 ) / 637213

GCD(643, 991) = 637213 / 637213

GCD(643, 991) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 562

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

LCM(1, 562) = 562

GCD(1, 562) = ( 1 x 562 ) / 562

GCD(1, 562) = 562 / 562

GCD(1, 562) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 883

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

LCM(1, 883) = 883

GCD(1, 883) = ( 1 x 883 ) / 883

GCD(1, 883) = 883 / 883

GCD(1, 883) = 1

GCD of 643, 991, 562, 883 is 1
