Given numbers are 195, 517, 603, 815

The list of prime factors of all numbers are

Prime factors of 195 are 3 x 5 x 13

Prime factors of 517 are 11 x 47

Prime factors of 603 are 3 x 3 x 67

Prime factors of 815 are 5 x 163

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

Given numbers are 195, 517, 603, 815

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

Apply this formula for all numbers.

Step1:

LCM(195, 517) = 100815

GCD(195, 517) = ( 195 x 517 ) / 100815

= 195 / 517

= 195

Step2:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 195, 517, 603, 815 is 1
