Given numbers are 431, 447, 425, 621

The list of prime factors of all numbers are

Prime factors of 431 are 431

Prime factors of 447 are 3 x 149

Prime factors of 425 are 5 x 5 x 17

Prime factors of 621 are 3 x 3 x 3 x 23

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

Given numbers are 431, 447, 425, 621

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

Apply this formula for all numbers.

Step1:

LCM(431, 447) = 192657

GCD(431, 447) = ( 431 x 447 ) / 192657

= 431 / 447

= 431

Step2:

LCM(1, 425) = 425

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

= 1 / 425

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 431, 447, 425, 621 is 1
