Therefore, GCD of numbers 25, 455, 417, 706 is 1

Given Input Data is 25, 455, 417, 706

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

Prime Factorization of 25 is 5 x 5

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 417 is 3 x 139

Prime Factorization of 706 is 2 x 353

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(25, 455) = 2275

GCD(25, 455) = ( 25 x 455 ) / 2275

GCD(25, 455) = 11375 / 2275

GCD(25, 455) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 417

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

LCM(5, 417) = 2085

GCD(5, 417) = ( 5 x 417 ) / 2085

GCD(5, 417) = 2085 / 2085

GCD(5, 417) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 706

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

LCM(1, 706) = 706

GCD(1, 706) = ( 1 x 706 ) / 706

GCD(1, 706) = 706 / 706

GCD(1, 706) = 1

GCD of 25, 455, 417, 706 is 1
