Given numbers are 243, 330, 647, 765

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 647 are 647

Prime factors of 765 are 3 x 3 x 5 x 17

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

Given numbers are 243, 330, 647, 765

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, 647) = 1941

GCD(3, 647) = ( 3 x 647 ) / 1941

= 3 / 647

= 3

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 243, 330, 647, 765 is 1
