The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 464 are 2 x 2 x 2 x 2 x 29

Prime factors of 789 are 3 x 263

Prime factors of 145 are 5 x 29

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

Given numbers are 423, 464, 789, 145

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

Apply this formula for all numbers.

Step1:

LCM(423, 464) = 196272

GCD(423, 464) = ( 423 x 464 ) / 196272

= 423 / 464

= 423

Step2:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 423, 464, 789, 145 is 1
