Given numbers are 417, 821, 270, 205

The list of prime factors of all numbers are

Prime factors of 417 are 3 x 139

Prime factors of 821 are 821

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

Prime factors of 205 are 5 x 41

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

Given numbers are 417, 821, 270, 205

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

Apply this formula for all numbers.

Step1:

LCM(417, 821) = 342357

GCD(417, 821) = ( 417 x 821 ) / 342357

= 417 / 821

= 417

Step2:

LCM(1, 270) = 270

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

= 1 / 270

= 1

Step3:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

So, Greatest Common Divisor of 417, 821, 270, 205 is 1
