Therefore, GCD of numbers 479, 131, 21, 865 is 1

Given Input Data is 479, 131, 21, 865

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

Prime Factorization of 479 is 479

Prime Factorization of 131 is 131

Prime Factorization of 21 is 3 x 7

Prime Factorization of 865 is 5 x 173

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(479, 131) = 62749

GCD(479, 131) = ( 479 x 131 ) / 62749

GCD(479, 131) = 62749 / 62749

GCD(479, 131) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

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

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 865

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

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

GCD(1, 865) = 865 / 865

GCD(1, 865) = 1

GCD of 479, 131, 21, 865 is 1
