Given numbers are 318, 756, 685, 805

The list of prime factors of all numbers are

Prime factors of 318 are 2 x 3 x 53

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 685 are 5 x 137

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 318, 756, 685, 805

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

Apply this formula for all numbers.

Step1:

LCM(318, 756) = 40068

GCD(318, 756) = ( 318 x 756 ) / 40068

= 318 / 756

= 318

Step2:

LCM(6, 685) = 4110

GCD(6, 685) = ( 6 x 685 ) / 4110

= 6 / 685

= 6

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 318, 756, 685, 805 is 1
