Given numbers are 430, 345, 646, 437

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 345 are 3 x 5 x 23

Prime factors of 646 are 2 x 17 x 19

Prime factors of 437 are 19 x 23

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

Given numbers are 430, 345, 646, 437

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

Apply this formula for all numbers.

Step1:

LCM(430, 345) = 29670

GCD(430, 345) = ( 430 x 345 ) / 29670

= 430 / 345

= 430

Step2:

LCM(5, 646) = 3230

GCD(5, 646) = ( 5 x 646 ) / 3230

= 5 / 646

= 5

Step3:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

So, Greatest Common Divisor of 430, 345, 646, 437 is 1
