Given numbers are 768, 814, 905, 663

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 814 are 2 x 11 x 37

Prime factors of 905 are 5 x 181

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 768, 814, 905, 663

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

Apply this formula for all numbers.

Step1:

LCM(768, 814) = 312576

GCD(768, 814) = ( 768 x 814 ) / 312576

= 768 / 814

= 768

Step2:

LCM(2, 905) = 1810

GCD(2, 905) = ( 2 x 905 ) / 1810

= 2 / 905

= 2

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 768, 814, 905, 663 is 1
