Given numbers are 287, 163, 154, 256

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 163 are 163

Prime factors of 154 are 2 x 7 x 11

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 287, 163, 154, 256

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

Apply this formula for all numbers.

Step1:

LCM(287, 163) = 46781

GCD(287, 163) = ( 287 x 163 ) / 46781

= 287 / 163

= 287

Step2:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

Step3:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 287, 163, 154, 256 is 1
