Given numbers are 403, 430, 189, 249

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 430 are 2 x 5 x 43

Prime factors of 189 are 3 x 3 x 3 x 7

Prime factors of 249 are 3 x 83

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

Given numbers are 403, 430, 189, 249

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

Apply this formula for all numbers.

Step1:

LCM(403, 430) = 173290

GCD(403, 430) = ( 403 x 430 ) / 173290

= 403 / 430

= 403

Step2:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 403, 430, 189, 249 is 1
