Given numbers are 243, 258, 276, 641

The list of prime factors of all numbers are

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

Prime factors of 258 are 2 x 3 x 43

Prime factors of 276 are 2 x 2 x 3 x 23

Prime factors of 641 are 641

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

Given numbers are 243, 258, 276, 641

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

Apply this formula for all numbers.

Step1:

LCM(243, 258) = 20898

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

= 243 / 258

= 243

Step2:

LCM(3, 276) = 276

GCD(3, 276) = ( 3 x 276 ) / 276

= 3 / 276

= 3

Step3:

LCM(3, 641) = 1923

GCD(3, 641) = ( 3 x 641 ) / 1923

= 3 / 641

= 3

So, Greatest Common Divisor of 243, 258, 276, 641 is 1
