Given numbers are 768, 216, 397, 409

The list of prime factors of all numbers are

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 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 397 are 397

Prime factors of 409 are 409

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

Given numbers are 768, 216, 397, 409

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

Apply this formula for all numbers.

Step1:

LCM(768, 216) = 6912

GCD(768, 216) = ( 768 x 216 ) / 6912

= 768 / 216

= 768

Step2:

LCM(24, 397) = 9528

GCD(24, 397) = ( 24 x 397 ) / 9528

= 24 / 397

= 24

Step3:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

So, Greatest Common Divisor of 768, 216, 397, 409 is 1
