Given numbers are 398, 517, 332, 656

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 517 are 11 x 47

Prime factors of 332 are 2 x 2 x 83

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Given numbers are 398, 517, 332, 656

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

Apply this formula for all numbers.

Step1:

LCM(398, 517) = 205766

GCD(398, 517) = ( 398 x 517 ) / 205766

= 398 / 517

= 398

Step2:

LCM(1, 332) = 332

GCD(1, 332) = ( 1 x 332 ) / 332

= 1 / 332

= 1

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 398, 517, 332, 656 is 1
