Given numbers are 280, 231, 495, 422

The list of prime factors of all numbers are

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

Prime factors of 231 are 3 x 7 x 11

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 422 are 2 x 211

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

Given numbers are 280, 231, 495, 422

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

Apply this formula for all numbers.

Step1:

LCM(280, 231) = 9240

GCD(280, 231) = ( 280 x 231 ) / 9240

= 280 / 231

= 280

Step2:

LCM(7, 495) = 3465

GCD(7, 495) = ( 7 x 495 ) / 3465

= 7 / 495

= 7

Step3:

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

= 1 / 422

= 1

So, Greatest Common Divisor of 280, 231, 495, 422 is 1
