The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 685 are 5 x 137

Prime factors of 245 are 5 x 7 x 7

Prime factors of 488 are 2 x 2 x 2 x 61

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

Given numbers are 515, 685, 245, 488

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

Apply this formula for all numbers.

Step1:

LCM(515, 685) = 70555

GCD(515, 685) = ( 515 x 685 ) / 70555

= 515 / 685

= 515

Step2:

LCM(5, 245) = 245

GCD(5, 245) = ( 5 x 245 ) / 245

= 5 / 245

= 5

Step3:

LCM(5, 488) = 2440

GCD(5, 488) = ( 5 x 488 ) / 2440

= 5 / 488

= 5

So, Greatest Common Divisor of 515, 685, 245, 488 is 1
