Given numbers are 780, 939, 219, 310

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 939 are 3 x 313

Prime factors of 219 are 3 x 73

Prime factors of 310 are 2 x 5 x 31

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

Given numbers are 780, 939, 219, 310

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

Apply this formula for all numbers.

Step1:

LCM(780, 939) = 244140

GCD(780, 939) = ( 780 x 939 ) / 244140

= 780 / 939

= 780

Step2:

LCM(3, 219) = 219

GCD(3, 219) = ( 3 x 219 ) / 219

= 3 / 219

= 3

Step3:

LCM(3, 310) = 930

GCD(3, 310) = ( 3 x 310 ) / 930

= 3 / 310

= 3

So, Greatest Common Divisor of 780, 939, 219, 310 is 1
