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 344 are 2 x 2 x 2 x 43

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 959 are 7 x 137

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

Given numbers are 780, 344, 340, 959

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

Apply this formula for all numbers.

Step1:

LCM(780, 344) = 67080

GCD(780, 344) = ( 780 x 344 ) / 67080

= 780 / 344

= 780

Step2:

LCM(4, 340) = 340

GCD(4, 340) = ( 4 x 340 ) / 340

= 4 / 340

= 4

Step3:

LCM(4, 959) = 3836

GCD(4, 959) = ( 4 x 959 ) / 3836

= 4 / 959

= 4

So, Greatest Common Divisor of 780, 344, 340, 959 is 1
