Given numbers are 261, 644, 467, 205

The list of prime factors of all numbers are

Prime factors of 261 are 3 x 3 x 29

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 467 are 467

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 261, 644, 467, 205

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

Apply this formula for all numbers.

Step1:

LCM(261, 644) = 168084

GCD(261, 644) = ( 261 x 644 ) / 168084

= 261 / 644

= 261

Step2:

LCM(1, 467) = 467

GCD(1, 467) = ( 1 x 467 ) / 467

= 1 / 467

= 1

Step3:

LCM(1, 205) = 205

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

= 1 / 205

= 1

So, Greatest Common Divisor of 261, 644, 467, 205 is 1
