Given numbers are 231, 190, 430, 280

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 190 are 2 x 5 x 19

Prime factors of 430 are 2 x 5 x 43

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 231, 190, 430, 280

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

Apply this formula for all numbers.

Step1:

LCM(231, 190) = 43890

GCD(231, 190) = ( 231 x 190 ) / 43890

= 231 / 190

= 231

Step2:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 231, 190, 430, 280 is 1
