The list of prime factors of all numbers are

Prime factors of 847 are 7 x 11 x 11

Prime factors of 195 are 3 x 5 x 13

Prime factors of 345 are 3 x 5 x 23

Prime factors of 421 are 421

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

Given numbers are 847, 195, 345, 421

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

Apply this formula for all numbers.

Step1:

LCM(847, 195) = 165165

GCD(847, 195) = ( 847 x 195 ) / 165165

= 847 / 195

= 847

Step2:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 847, 195, 345, 421 is 1
