The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 205 are 5 x 41

Prime factors of 843 are 3 x 281

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

Given numbers are 815, 693, 205, 843

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

Apply this formula for all numbers.

Step1:

LCM(815, 693) = 564795

GCD(815, 693) = ( 815 x 693 ) / 564795

= 815 / 693

= 815

Step2:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

Step3:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

So, Greatest Common Divisor of 815, 693, 205, 843 is 1
