Given numbers are 856, 939, 840, 505

The list of prime factors of all numbers are

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 939 are 3 x 313

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 505 are 5 x 101

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

Given numbers are 856, 939, 840, 505

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

Apply this formula for all numbers.

Step1:

LCM(856, 939) = 803784

GCD(856, 939) = ( 856 x 939 ) / 803784

= 856 / 939

= 856

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 856, 939, 840, 505 is 1
