Given numbers are 680, 349, 103, 305

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 349 are 349

Prime factors of 103 are 103

Prime factors of 305 are 5 x 61

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

Given numbers are 680, 349, 103, 305

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

Apply this formula for all numbers.

Step1:

LCM(680, 349) = 237320

GCD(680, 349) = ( 680 x 349 ) / 237320

= 680 / 349

= 680

Step2:

LCM(1, 103) = 103

GCD(1, 103) = ( 1 x 103 ) / 103

= 1 / 103

= 1

Step3:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

So, Greatest Common Divisor of 680, 349, 103, 305 is 1
