Given numbers are 806, 515, 863, 621

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 515 are 5 x 103

Prime factors of 863 are 863

Prime factors of 621 are 3 x 3 x 3 x 23

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

Given numbers are 806, 515, 863, 621

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

Apply this formula for all numbers.

Step1:

LCM(806, 515) = 415090

GCD(806, 515) = ( 806 x 515 ) / 415090

= 806 / 515

= 806

Step2:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 806, 515, 863, 621 is 1
