Given numbers are 330, 768, 456, 247

The list of prime factors of all numbers are

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 247 are 13 x 19

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

Given numbers are 330, 768, 456, 247

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

Apply this formula for all numbers.

Step1:

LCM(330, 768) = 42240

GCD(330, 768) = ( 330 x 768 ) / 42240

= 330 / 768

= 330

Step2:

LCM(6, 456) = 456

GCD(6, 456) = ( 6 x 456 ) / 456

= 6 / 456

= 6

Step3:

LCM(6, 247) = 1482

GCD(6, 247) = ( 6 x 247 ) / 1482

= 6 / 247

= 6

So, Greatest Common Divisor of 330, 768, 456, 247 is 1
