Therefore, GCD of numbers 485, 905, 964, 523 is 1

Given Input Data is 485, 905, 964, 523

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

Prime Factorization of 485 is 5 x 97

Prime Factorization of 905 is 5 x 181

Prime Factorization of 964 is 2 x 2 x 241

Prime Factorization of 523 is 523

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(485, 905) = 87785

GCD(485, 905) = ( 485 x 905 ) / 87785

GCD(485, 905) = 438925 / 87785

GCD(485, 905) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 964

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

LCM(5, 964) = 4820

GCD(5, 964) = ( 5 x 964 ) / 4820

GCD(5, 964) = 4820 / 4820

GCD(5, 964) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 523

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

LCM(1, 523) = 523

GCD(1, 523) = ( 1 x 523 ) / 523

GCD(1, 523) = 523 / 523

GCD(1, 523) = 1

GCD of 485, 905, 964, 523 is 1
