Given numbers are 516, 891, 686, 939

The list of prime factors of all numbers are

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

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

Prime factors of 939 are 3 x 313

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

Given numbers are 516, 891, 686, 939

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

Apply this formula for all numbers.

Step1:

LCM(516, 891) = 153252

GCD(516, 891) = ( 516 x 891 ) / 153252

= 516 / 891

= 516

Step2:

LCM(3, 686) = 2058

GCD(3, 686) = ( 3 x 686 ) / 2058

= 3 / 686

= 3

Step3:

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

= 1 / 939

= 1

So, Greatest Common Divisor of 516, 891, 686, 939 is 1
