Given numbers are 810, 688, 685, 191

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 685 are 5 x 137

Prime factors of 191 are 191

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

Given numbers are 810, 688, 685, 191

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

Apply this formula for all numbers.

Step1:

LCM(810, 688) = 278640

GCD(810, 688) = ( 810 x 688 ) / 278640

= 810 / 688

= 810

Step2:

LCM(2, 685) = 1370

GCD(2, 685) = ( 2 x 685 ) / 1370

= 2 / 685

= 2

Step3:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

So, Greatest Common Divisor of 810, 688, 685, 191 is 1
