Given numbers are 331, 640, 305, 190

The list of prime factors of all numbers are

Prime factors of 331 are 331

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 305 are 5 x 61

Prime factors of 190 are 2 x 5 x 19

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

Given numbers are 331, 640, 305, 190

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

Apply this formula for all numbers.

Step1:

LCM(331, 640) = 211840

GCD(331, 640) = ( 331 x 640 ) / 211840

= 331 / 640

= 331

Step2:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

Step3:

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

= 1 / 190

= 1

So, Greatest Common Divisor of 331, 640, 305, 190 is 1
