Given numbers are 813, 210, 522, 991

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 522 are 2 x 3 x 3 x 29

Prime factors of 991 are 991

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

Given numbers are 813, 210, 522, 991

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

Apply this formula for all numbers.

Step1:

LCM(813, 210) = 56910

GCD(813, 210) = ( 813 x 210 ) / 56910

= 813 / 210

= 813

Step2:

LCM(3, 522) = 522

GCD(3, 522) = ( 3 x 522 ) / 522

= 3 / 522

= 3

Step3:

LCM(3, 991) = 2973

GCD(3, 991) = ( 3 x 991 ) / 2973

= 3 / 991

= 3

So, Greatest Common Divisor of 813, 210, 522, 991 is 1
