We found the divisors of 626, 305, 84, 428 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 626, 305, 84, 428 is 1.

Therefore, GCD of numbers 626, 305, 84, 428 is 1

Given Input Data is 626, 305, 84, 428

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

Prime Factorization of 626 is 2 x 313

Prime Factorization of 305 is 5 x 61

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 428 is 2 x 2 x 107

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(626, 305) = 190930

GCD(626, 305) = ( 626 x 305 ) / 190930

GCD(626, 305) = 190930 / 190930

GCD(626, 305) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 84

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

LCM(1, 84) = 84

GCD(1, 84) = ( 1 x 84 ) / 84

GCD(1, 84) = 84 / 84

GCD(1, 84) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 428

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

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

GCD(1, 428) = 428 / 428

GCD(1, 428) = 1

GCD of 626, 305, 84, 428 is 1
