Therefore, GCD of numbers 587, 309, 58, 644 is 1

Given Input Data is 587, 309, 58, 644

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

Prime Factorization of 587 is 587

Prime Factorization of 309 is 3 x 103

Prime Factorization of 58 is 2 x 29

Prime Factorization of 644 is 2 x 2 x 7 x 23

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(587, 309) = 181383

GCD(587, 309) = ( 587 x 309 ) / 181383

GCD(587, 309) = 181383 / 181383

GCD(587, 309) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 58

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

LCM(1, 58) = 58

GCD(1, 58) = ( 1 x 58 ) / 58

GCD(1, 58) = 58 / 58

GCD(1, 58) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 644

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

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

GCD(1, 644) = 644 / 644

GCD(1, 644) = 1

GCD of 587, 309, 58, 644 is 1
