Given numbers are 688, 731, 805, 930

The list of prime factors of all numbers are

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

Prime factors of 731 are 17 x 43

Prime factors of 805 are 5 x 7 x 23

Prime factors of 930 are 2 x 3 x 5 x 31

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

Given numbers are 688, 731, 805, 930

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

Apply this formula for all numbers.

Step1:

LCM(688, 731) = 11696

GCD(688, 731) = ( 688 x 731 ) / 11696

= 688 / 731

= 688

Step2:

LCM(43, 805) = 34615

GCD(43, 805) = ( 43 x 805 ) / 34615

= 43 / 805

= 43

Step3:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

So, Greatest Common Divisor of 688, 731, 805, 930 is 1
