The list of prime factors of all numbers are

Prime factors of 369 are 3 x 3 x 41

Prime factors of 905 are 5 x 181

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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 369, 905, 780, 243

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

Apply this formula for all numbers.

Step1:

LCM(369, 905) = 333945

GCD(369, 905) = ( 369 x 905 ) / 333945

= 369 / 905

= 369

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 243) = 243

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

= 1 / 243

= 1

So, Greatest Common Divisor of 369, 905, 780, 243 is 1
