Given numbers are 230, 634, 639, 251

The list of prime factors of all numbers are

Prime factors of 230 are 2 x 5 x 23

Prime factors of 634 are 2 x 317

Prime factors of 639 are 3 x 3 x 71

Prime factors of 251 are 251

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

Given numbers are 230, 634, 639, 251

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

Apply this formula for all numbers.

Step1:

LCM(230, 634) = 72910

GCD(230, 634) = ( 230 x 634 ) / 72910

= 230 / 634

= 230

Step2:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

Step3:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

So, Greatest Common Divisor of 230, 634, 639, 251 is 1
