Given numbers are 430, 143, 645, 322

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 143 are 11 x 13

Prime factors of 645 are 3 x 5 x 43

Prime factors of 322 are 2 x 7 x 23

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

Given numbers are 430, 143, 645, 322

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

Apply this formula for all numbers.

Step1:

LCM(430, 143) = 61490

GCD(430, 143) = ( 430 x 143 ) / 61490

= 430 / 143

= 430

Step2:

LCM(1, 645) = 645

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

= 1 / 645

= 1

Step3:

LCM(1, 322) = 322

GCD(1, 322) = ( 1 x 322 ) / 322

= 1 / 322

= 1

So, Greatest Common Divisor of 430, 143, 645, 322 is 1
