Given numbers are 856, 420, 843, 191

The list of prime factors of all numbers are

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

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 843 are 3 x 281

Prime factors of 191 are 191

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

Given numbers are 856, 420, 843, 191

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

Apply this formula for all numbers.

Step1:

LCM(856, 420) = 89880

GCD(856, 420) = ( 856 x 420 ) / 89880

= 856 / 420

= 856

Step2:

LCM(4, 843) = 3372

GCD(4, 843) = ( 4 x 843 ) / 3372

= 4 / 843

= 4

Step3:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

So, Greatest Common Divisor of 856, 420, 843, 191 is 1
