Given numbers are 831, 297, 530, 139

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 297 are 3 x 3 x 3 x 11

Prime factors of 530 are 2 x 5 x 53

Prime factors of 139 are 139

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

Given numbers are 831, 297, 530, 139

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

Apply this formula for all numbers.

Step1:

LCM(831, 297) = 82269

GCD(831, 297) = ( 831 x 297 ) / 82269

= 831 / 297

= 831

Step2:

LCM(3, 530) = 1590

GCD(3, 530) = ( 3 x 530 ) / 1590

= 3 / 530

= 3

Step3:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1

So, Greatest Common Divisor of 831, 297, 530, 139 is 1
