Given numbers are 398, 425, 305, 624

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 425 are 5 x 5 x 17

Prime factors of 305 are 5 x 61

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

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

Given numbers are 398, 425, 305, 624

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

Apply this formula for all numbers.

Step1:

LCM(398, 425) = 169150

GCD(398, 425) = ( 398 x 425 ) / 169150

= 398 / 425

= 398

Step2:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 398, 425, 305, 624 is 1
