Given numbers are 258, 345, 129, 205

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 345 are 3 x 5 x 23

Prime factors of 129 are 3 x 43

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 258, 345, 129, 205

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

Apply this formula for all numbers.

Step1:

LCM(258, 345) = 29670

GCD(258, 345) = ( 258 x 345 ) / 29670

= 258 / 345

= 258

Step2:

LCM(3, 129) = 129

GCD(3, 129) = ( 3 x 129 ) / 129

= 3 / 129

= 3

Step3:

LCM(3, 205) = 615

GCD(3, 205) = ( 3 x 205 ) / 615

= 3 / 205

= 3

So, Greatest Common Divisor of 258, 345, 129, 205 is 1
