Given numbers are 843, 438, 693, 415

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 438 are 2 x 3 x 73

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

Prime factors of 415 are 5 x 83

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

Given numbers are 843, 438, 693, 415

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

Apply this formula for all numbers.

Step1:

LCM(843, 438) = 123078

GCD(843, 438) = ( 843 x 438 ) / 123078

= 843 / 438

= 843

Step2:

LCM(3, 693) = 693

GCD(3, 693) = ( 3 x 693 ) / 693

= 3 / 693

= 3

Step3:

LCM(3, 415) = 1245

GCD(3, 415) = ( 3 x 415 ) / 1245

= 3 / 415

= 3

So, Greatest Common Divisor of 843, 438, 693, 415 is 1
