Given numbers are 205, 561, 928, 270

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 561 are 3 x 11 x 17

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

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

Given numbers are 205, 561, 928, 270

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

Apply this formula for all numbers.

Step1:

LCM(205, 561) = 115005

GCD(205, 561) = ( 205 x 561 ) / 115005

= 205 / 561

= 205

Step2:

LCM(1, 928) = 928

GCD(1, 928) = ( 1 x 928 ) / 928

= 1 / 928

= 1

Step3:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

So, Greatest Common Divisor of 205, 561, 928, 270 is 1
