Given numbers are 872, 774, 779, 686

The list of prime factors of all numbers are

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

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 779 are 19 x 41

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 872, 774, 779, 686

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

Apply this formula for all numbers.

Step1:

LCM(872, 774) = 337464

GCD(872, 774) = ( 872 x 774 ) / 337464

= 872 / 774

= 872

Step2:

LCM(2, 779) = 1558

GCD(2, 779) = ( 2 x 779 ) / 1558

= 2 / 779

= 2

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 872, 774, 779, 686 is 1
