Given numbers are 530, 605, 868, 819

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 605 are 5 x 11 x 11

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 819 are 3 x 3 x 7 x 13

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

Given numbers are 530, 605, 868, 819

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

Apply this formula for all numbers.

Step1:

LCM(530, 605) = 64130

GCD(530, 605) = ( 530 x 605 ) / 64130

= 530 / 605

= 530

Step2:

LCM(5, 868) = 4340

GCD(5, 868) = ( 5 x 868 ) / 4340

= 5 / 868

= 5

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 530, 605, 868, 819 is 1
