Given numbers are 243, 330, 746, 815

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 330 are 2 x 3 x 5 x 11

Prime factors of 746 are 2 x 373

Prime factors of 815 are 5 x 163

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

Given numbers are 243, 330, 746, 815

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

Apply this formula for all numbers.

Step1:

LCM(243, 330) = 26730

GCD(243, 330) = ( 243 x 330 ) / 26730

= 243 / 330

= 243

Step2:

LCM(3, 746) = 2238

GCD(3, 746) = ( 3 x 746 ) / 2238

= 3 / 746

= 3

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 243, 330, 746, 815 is 1
