Given numbers are 306, 638, 811, 425

The list of prime factors of all numbers are

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 638 are 2 x 11 x 29

Prime factors of 811 are 811

Prime factors of 425 are 5 x 5 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 306, 638, 811, 425

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(306, 638) = 97614

GCD(306, 638) = ( 306 x 638 ) / 97614

= 306 / 638

= 306

Step2:

LCM(2, 811) = 1622

GCD(2, 811) = ( 2 x 811 ) / 1622

= 2 / 811

= 2

Step3:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

So, Greatest Common Divisor of 306, 638, 811, 425 is 1
