Given numbers are 507, 404, 398, 243

The list of prime factors of all numbers are

Prime factors of 507 are 3 x 13 x 13

Prime factors of 404 are 2 x 2 x 101

Prime factors of 398 are 2 x 199

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 507, 404, 398, 243

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

Apply this formula for all numbers.

Step1:

LCM(507, 404) = 204828

GCD(507, 404) = ( 507 x 404 ) / 204828

= 507 / 404

= 507

Step2:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

Step3:

LCM(1, 243) = 243

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

= 1 / 243

= 1

So, Greatest Common Divisor of 507, 404, 398, 243 is 1
