The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 823 are 823

Prime factors of 735 are 3 x 5 x 7 x 7

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 438, 823, 735, 288

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

Apply this formula for all numbers.

Step1:

LCM(438, 823) = 360474

GCD(438, 823) = ( 438 x 823 ) / 360474

= 438 / 823

= 438

Step2:

LCM(1, 735) = 735

GCD(1, 735) = ( 1 x 735 ) / 735

= 1 / 735

= 1

Step3:

LCM(1, 288) = 288

GCD(1, 288) = ( 1 x 288 ) / 288

= 1 / 288

= 1

So, Greatest Common Divisor of 438, 823, 735, 288 is 1
