The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

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

Prime factors of 614 are 2 x 307

Prime factors of 398 are 2 x 199

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

Given numbers are 245, 340, 614, 398

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

Apply this formula for all numbers.

Step1:

LCM(245, 340) = 16660

GCD(245, 340) = ( 245 x 340 ) / 16660

= 245 / 340

= 245

Step2:

LCM(5, 614) = 3070

GCD(5, 614) = ( 5 x 614 ) / 3070

= 5 / 614

= 5

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 245, 340, 614, 398 is 1
