Given numbers are 216, 639, 251, 814

The list of prime factors of all numbers are

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 639 are 3 x 3 x 71

Prime factors of 251 are 251

Prime factors of 814 are 2 x 11 x 37

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

Given numbers are 216, 639, 251, 814

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

Apply this formula for all numbers.

Step1:

LCM(216, 639) = 15336

GCD(216, 639) = ( 216 x 639 ) / 15336

= 216 / 639

= 216

Step2:

LCM(9, 251) = 2259

GCD(9, 251) = ( 9 x 251 ) / 2259

= 9 / 251

= 9

Step3:

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

= 1 / 814

= 1

So, Greatest Common Divisor of 216, 639, 251, 814 is 1
