Given numbers are 243, 273, 648, 845

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 273 are 3 x 7 x 13

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 845 are 5 x 13 x 13

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

Given numbers are 243, 273, 648, 845

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

Apply this formula for all numbers.

Step1:

LCM(243, 273) = 22113

GCD(243, 273) = ( 243 x 273 ) / 22113

= 243 / 273

= 243

Step2:

LCM(3, 648) = 648

GCD(3, 648) = ( 3 x 648 ) / 648

= 3 / 648

= 3

Step3:

LCM(3, 845) = 2535

GCD(3, 845) = ( 3 x 845 ) / 2535

= 3 / 845

= 3

So, Greatest Common Divisor of 243, 273, 648, 845 is 1
