Given numbers are 711, 793, 645, 456

The list of prime factors of all numbers are

Prime factors of 711 are 3 x 3 x 79

Prime factors of 793 are 13 x 61

Prime factors of 645 are 3 x 5 x 43

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Given numbers are 711, 793, 645, 456

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

Apply this formula for all numbers.

Step1:

LCM(711, 793) = 563823

GCD(711, 793) = ( 711 x 793 ) / 563823

= 711 / 793

= 711

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 711, 793, 645, 456 is 1
