Given numbers are 243, 905, 816, 446

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 905 are 5 x 181

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 446 are 2 x 223

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

Given numbers are 243, 905, 816, 446

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

Apply this formula for all numbers.

Step1:

LCM(243, 905) = 219915

GCD(243, 905) = ( 243 x 905 ) / 219915

= 243 / 905

= 243

Step2:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

Step3:

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

= 1 / 446

= 1

So, Greatest Common Divisor of 243, 905, 816, 446 is 1
