Given numbers are 340, 190, 786, 309

The list of prime factors of all numbers are

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

Prime factors of 190 are 2 x 5 x 19

Prime factors of 786 are 2 x 3 x 131

Prime factors of 309 are 3 x 103

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

Given numbers are 340, 190, 786, 309

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

Apply this formula for all numbers.

Step1:

LCM(340, 190) = 6460

GCD(340, 190) = ( 340 x 190 ) / 6460

= 340 / 190

= 340

Step2:

LCM(10, 786) = 3930

GCD(10, 786) = ( 10 x 786 ) / 3930

= 10 / 786

= 10

Step3:

LCM(2, 309) = 618

GCD(2, 309) = ( 2 x 309 ) / 618

= 2 / 309

= 2

So, Greatest Common Divisor of 340, 190, 786, 309 is 1
