Given numbers are 258, 243, 122, 403

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 122 are 2 x 61

Prime factors of 403 are 13 x 31

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

Given numbers are 258, 243, 122, 403

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

Apply this formula for all numbers.

Step1:

LCM(258, 243) = 20898

GCD(258, 243) = ( 258 x 243 ) / 20898

= 258 / 243

= 258

Step2:

LCM(3, 122) = 366

GCD(3, 122) = ( 3 x 122 ) / 366

= 3 / 122

= 3

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 258, 243, 122, 403 is 1
