Given numbers are 768, 168, 905, 306

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 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 905 are 5 x 181

Prime factors of 306 are 2 x 3 x 3 x 17

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

Given numbers are 768, 168, 905, 306

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

Apply this formula for all numbers.

Step1:

LCM(768, 168) = 5376

GCD(768, 168) = ( 768 x 168 ) / 5376

= 768 / 168

= 768

Step2:

LCM(24, 905) = 21720

GCD(24, 905) = ( 24 x 905 ) / 21720

= 24 / 905

= 24

Step3:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 768, 168, 905, 306 is 1
