Given numbers are 791, 810, 663, 423

The list of prime factors of all numbers are

Prime factors of 791 are 7 x 113

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 663 are 3 x 13 x 17

Prime factors of 423 are 3 x 3 x 47

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

Given numbers are 791, 810, 663, 423

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

Apply this formula for all numbers.

Step1:

LCM(791, 810) = 640710

GCD(791, 810) = ( 791 x 810 ) / 640710

= 791 / 810

= 791

Step2:

LCM(1, 663) = 663

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

= 1 / 663

= 1

Step3:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

So, Greatest Common Divisor of 791, 810, 663, 423 is 1
