Given numbers are 831, 991, 936, 828

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 991 are 991

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 831, 991, 936, 828

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

Apply this formula for all numbers.

Step1:

LCM(831, 991) = 823521

GCD(831, 991) = ( 831 x 991 ) / 823521

= 831 / 991

= 831

Step2:

LCM(1, 936) = 936

GCD(1, 936) = ( 1 x 936 ) / 936

= 1 / 936

= 1

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 831, 991, 936, 828 is 1
