Given numbers are 287, 920, 422, 320

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 422 are 2 x 211

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 287, 920, 422, 320

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

Apply this formula for all numbers.

Step1:

LCM(287, 920) = 264040

GCD(287, 920) = ( 287 x 920 ) / 264040

= 287 / 920

= 287

Step2:

LCM(1, 422) = 422

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

= 1 / 422

= 1

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 287, 920, 422, 320 is 1
