Given numbers are 780, 385, 880, 839

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 385 are 5 x 7 x 11

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

Prime factors of 839 are 839

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

Given numbers are 780, 385, 880, 839

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

Apply this formula for all numbers.

Step1:

LCM(780, 385) = 60060

GCD(780, 385) = ( 780 x 385 ) / 60060

= 780 / 385

= 780

Step2:

LCM(5, 880) = 880

GCD(5, 880) = ( 5 x 880 ) / 880

= 5 / 880

= 5

Step3:

LCM(5, 839) = 4195

GCD(5, 839) = ( 5 x 839 ) / 4195

= 5 / 839

= 5

So, Greatest Common Divisor of 780, 385, 880, 839 is 1
