Given numbers are 831, 820, 788, 249

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 788 are 2 x 2 x 197

Prime factors of 249 are 3 x 83

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

Given numbers are 831, 820, 788, 249

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

Apply this formula for all numbers.

Step1:

LCM(831, 820) = 681420

GCD(831, 820) = ( 831 x 820 ) / 681420

= 831 / 820

= 831

Step2:

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

= 1 / 788

= 1

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 831, 820, 788, 249 is 1
