The list of prime factors of all numbers are

Prime factors of 723 are 3 x 241

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 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 979 are 11 x 89

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

Given numbers are 723, 768, 440, 979

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

Apply this formula for all numbers.

Step1:

LCM(723, 768) = 185088

GCD(723, 768) = ( 723 x 768 ) / 185088

= 723 / 768

= 723

Step2:

LCM(3, 440) = 1320

GCD(3, 440) = ( 3 x 440 ) / 1320

= 3 / 440

= 3

Step3:

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

= 1 / 979

= 1

So, Greatest Common Divisor of 723, 768, 440, 979 is 1
