We found the divisors of 254, 605, 917, 435 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 254, 605, 917, 435 is 1.

Therefore, GCD of numbers 254, 605, 917, 435 is 1

Given Input Data is 254, 605, 917, 435

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

Prime Factorization of 254 is 2 x 127

Prime Factorization of 605 is 5 x 11 x 11

Prime Factorization of 917 is 7 x 131

Prime Factorization of 435 is 3 x 5 x 29

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(254, 605) = 153670

GCD(254, 605) = ( 254 x 605 ) / 153670

GCD(254, 605) = 153670 / 153670

GCD(254, 605) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 917

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

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

GCD(1, 917) = 917 / 917

GCD(1, 917) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 435

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

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

GCD(1, 435) = 435 / 435

GCD(1, 435) = 1

GCD of 254, 605, 917, 435 is 1
