Given numbers are 831, 425, 620, 664

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 425 are 5 x 5 x 17

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 831, 425, 620, 664

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

Apply this formula for all numbers.

Step1:

LCM(831, 425) = 353175

GCD(831, 425) = ( 831 x 425 ) / 353175

= 831 / 425

= 831

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 831, 425, 620, 664 is 1
