Given numbers are 324, 558, 643, 243

The list of prime factors of all numbers are

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 643 are 643

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

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

Given numbers are 324, 558, 643, 243

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

Apply this formula for all numbers.

Step1:

LCM(324, 558) = 10044

GCD(324, 558) = ( 324 x 558 ) / 10044

= 324 / 558

= 324

Step2:

LCM(18, 643) = 11574

GCD(18, 643) = ( 18 x 643 ) / 11574

= 18 / 643

= 18

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 324, 558, 643, 243 is 1
