Given numbers are 686, 310, 805, 916

The list of prime factors of all numbers are

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

Prime factors of 310 are 2 x 5 x 31

Prime factors of 805 are 5 x 7 x 23

Prime factors of 916 are 2 x 2 x 229

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

Given numbers are 686, 310, 805, 916

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

Apply this formula for all numbers.

Step1:

LCM(686, 310) = 106330

GCD(686, 310) = ( 686 x 310 ) / 106330

= 686 / 310

= 686

Step2:

LCM(2, 805) = 1610

GCD(2, 805) = ( 2 x 805 ) / 1610

= 2 / 805

= 2

Step3:

LCM(1, 916) = 916

GCD(1, 916) = ( 1 x 916 ) / 916

= 1 / 916

= 1

So, Greatest Common Divisor of 686, 310, 805, 916 is 1
