Given numbers are 768, 321, 85, 521

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 321 are 3 x 107

Prime factors of 85 are 5 x 17

Prime factors of 521 are 521

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

Given numbers are 768, 321, 85, 521

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

Apply this formula for all numbers.

Step1:

LCM(768, 321) = 82176

GCD(768, 321) = ( 768 x 321 ) / 82176

= 768 / 321

= 768

Step2:

LCM(3, 85) = 255

GCD(3, 85) = ( 3 x 85 ) / 255

= 3 / 85

= 3

Step3:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

So, Greatest Common Divisor of 768, 321, 85, 521 is 1
