The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 865 are 5 x 173

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 221 are 13 x 17

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

Given numbers are 655, 865, 940, 221

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

Apply this formula for all numbers.

Step1:

LCM(655, 865) = 113315

GCD(655, 865) = ( 655 x 865 ) / 113315

= 655 / 865

= 655

Step2:

LCM(5, 940) = 940

GCD(5, 940) = ( 5 x 940 ) / 940

= 5 / 940

= 5

Step3:

LCM(5, 221) = 1105

GCD(5, 221) = ( 5 x 221 ) / 1105

= 5 / 221

= 5

So, Greatest Common Divisor of 655, 865, 940, 221 is 1
