Given numbers are 685, 680, 858, 794

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 794 are 2 x 397

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

Given numbers are 685, 680, 858, 794

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

Apply this formula for all numbers.

Step1:

LCM(685, 680) = 93160

GCD(685, 680) = ( 685 x 680 ) / 93160

= 685 / 680

= 685

Step2:

LCM(5, 858) = 4290

GCD(5, 858) = ( 5 x 858 ) / 4290

= 5 / 858

= 5

Step3:

LCM(1, 794) = 794

GCD(1, 794) = ( 1 x 794 ) / 794

= 1 / 794

= 1

So, Greatest Common Divisor of 685, 680, 858, 794 is 1
