The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 487 are 487

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 430, 487, 423

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

Apply this formula for all numbers.

Step1:

LCM(430, 487) = 209410

GCD(430, 487) = ( 430 x 487 ) / 209410

= 430 / 487

= 430

Step2:

LCM(1, 423) = 423

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

= 1 / 423

= 1

So, Greatest Common Divisor of 430, 487, 423 is 1
