Given numbers are 390, 676, 602, 843

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 676 are 2 x 2 x 13 x 13

Prime factors of 602 are 2 x 7 x 43

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 390, 676, 602, 843

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

Apply this formula for all numbers.

Step1:

LCM(390, 676) = 10140

GCD(390, 676) = ( 390 x 676 ) / 10140

= 390 / 676

= 390

Step2:

LCM(26, 602) = 7826

GCD(26, 602) = ( 26 x 602 ) / 7826

= 26 / 602

= 26

Step3:

LCM(2, 843) = 1686

GCD(2, 843) = ( 2 x 843 ) / 1686

= 2 / 843

= 2

So, Greatest Common Divisor of 390, 676, 602, 843 is 1
