Given numbers are 218, 360, 422, 257

The list of prime factors of all numbers are

Prime factors of 218 are 2 x 109

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 422 are 2 x 211

Prime factors of 257 are 257

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

Given numbers are 218, 360, 422, 257

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

Apply this formula for all numbers.

Step1:

LCM(218, 360) = 39240

GCD(218, 360) = ( 218 x 360 ) / 39240

= 218 / 360

= 218

Step2:

LCM(2, 422) = 422

GCD(2, 422) = ( 2 x 422 ) / 422

= 2 / 422

= 2

Step3:

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

= 2 / 257

= 2

So, Greatest Common Divisor of 218, 360, 422, 257 is 1
