Given numbers are 207, 222, 687, 556

The list of prime factors of all numbers are

Prime factors of 207 are 3 x 3 x 23

Prime factors of 222 are 2 x 3 x 37

Prime factors of 687 are 3 x 229

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 207, 222, 687, 556

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

Apply this formula for all numbers.

Step1:

LCM(207, 222) = 15318

GCD(207, 222) = ( 207 x 222 ) / 15318

= 207 / 222

= 207

Step2:

LCM(3, 687) = 687

GCD(3, 687) = ( 3 x 687 ) / 687

= 3 / 687

= 3

Step3:

LCM(3, 556) = 1668

GCD(3, 556) = ( 3 x 556 ) / 1668

= 3 / 556

= 3

So, Greatest Common Divisor of 207, 222, 687, 556 is 1
