Given numbers are 205, 540, 192, 221

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 192 are 2 x 2 x 2 x 2 x 2 x 2 x 3

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 205, 540, 192, 221

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

Apply this formula for all numbers.

Step1:

LCM(205, 540) = 22140

GCD(205, 540) = ( 205 x 540 ) / 22140

= 205 / 540

= 205

Step2:

LCM(5, 192) = 960

GCD(5, 192) = ( 5 x 192 ) / 960

= 5 / 192

= 5

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 205, 540, 192, 221 is 1
