Given numbers are 806, 621, 638, 516

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

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

Prime factors of 638 are 2 x 11 x 29

Prime factors of 516 are 2 x 2 x 3 x 43

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

Given numbers are 806, 621, 638, 516

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

Apply this formula for all numbers.

Step1:

LCM(806, 621) = 500526

GCD(806, 621) = ( 806 x 621 ) / 500526

= 806 / 621

= 806

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

So, Greatest Common Divisor of 806, 621, 638, 516 is 1
