Given numbers are 611, 191, 640, 305

The list of prime factors of all numbers are

Prime factors of 611 are 13 x 47

Prime factors of 191 are 191

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

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

Given numbers are 611, 191, 640, 305

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

Apply this formula for all numbers.

Step1:

LCM(611, 191) = 116701

GCD(611, 191) = ( 611 x 191 ) / 116701

= 611 / 191

= 611

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 305) = 305

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

= 1 / 305

= 1

So, Greatest Common Divisor of 611, 191, 640, 305 is 1
