Given numbers are 430, 644, 559, 312

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 559 are 13 x 43

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Given numbers are 430, 644, 559, 312

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

Apply this formula for all numbers.

Step1:

LCM(430, 644) = 138460

GCD(430, 644) = ( 430 x 644 ) / 138460

= 430 / 644

= 430

Step2:

LCM(2, 559) = 1118

GCD(2, 559) = ( 2 x 559 ) / 1118

= 2 / 559

= 2

Step3:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1

So, Greatest Common Divisor of 430, 644, 559, 312 is 1
