Given numbers are 806, 872, 660, 195

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 872 are 2 x 2 x 2 x 109

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 195 are 3 x 5 x 13

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

Given numbers are 806, 872, 660, 195

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

Apply this formula for all numbers.

Step1:

LCM(806, 872) = 351416

GCD(806, 872) = ( 806 x 872 ) / 351416

= 806 / 872

= 806

Step2:

LCM(2, 660) = 660

GCD(2, 660) = ( 2 x 660 ) / 660

= 2 / 660

= 2

Step3:

LCM(2, 195) = 390

GCD(2, 195) = ( 2 x 195 ) / 390

= 2 / 195

= 2

So, Greatest Common Divisor of 806, 872, 660, 195 is 1
