Given numbers are 831, 255, 940, 421

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 255 are 3 x 5 x 17

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 421 are 421

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

Given numbers are 831, 255, 940, 421

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

Apply this formula for all numbers.

Step1:

LCM(831, 255) = 70635

GCD(831, 255) = ( 831 x 255 ) / 70635

= 831 / 255

= 831

Step2:

LCM(3, 940) = 2820

GCD(3, 940) = ( 3 x 940 ) / 2820

= 3 / 940

= 3

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 831, 255, 940, 421 is 1
