The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 515 are 5 x 103

Prime factors of 424 are 2 x 2 x 2 x 53

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, 515, 424, 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, 515) = 25235

GCD(245, 515) = ( 245 x 515 ) / 25235

= 245 / 515

= 245

Step2:

LCM(5, 424) = 2120

GCD(5, 424) = ( 5 x 424 ) / 2120

= 5 / 424

= 5

Step3:

LCM(1, 398) = 398

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

= 1 / 398

= 1

So, Greatest Common Divisor of 245, 515, 424, 398 is 1
