Given numbers are 287, 617, 556, 228

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 617 are 617

Prime factors of 556 are 2 x 2 x 139

Prime factors of 228 are 2 x 2 x 3 x 19

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

Given numbers are 287, 617, 556, 228

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

Apply this formula for all numbers.

Step1:

LCM(287, 617) = 177079

GCD(287, 617) = ( 287 x 617 ) / 177079

= 287 / 617

= 287

Step2:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

Step3:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

So, Greatest Common Divisor of 287, 617, 556, 228 is 1
