Therefore, GCD of numbers 813, 438, 610, 635 is 1

Given Input Data is 813, 438, 610, 635

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

Prime Factorization of 813 is 3 x 271

Prime Factorization of 438 is 2 x 3 x 73

Prime Factorization of 610 is 2 x 5 x 61

Prime Factorization of 635 is 5 x 127

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(813, 438) = 118698

GCD(813, 438) = ( 813 x 438 ) / 118698

GCD(813, 438) = 356094 / 118698

GCD(813, 438) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 610

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

LCM(3, 610) = 1830

GCD(3, 610) = ( 3 x 610 ) / 1830

GCD(3, 610) = 1830 / 1830

GCD(3, 610) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 635

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

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

GCD(1, 635) = 635 / 635

GCD(1, 635) = 1

GCD of 813, 438, 610, 635 is 1
