Given numbers are 638, 214, 515, 255

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 214 are 2 x 107

Prime factors of 515 are 5 x 103

Prime factors of 255 are 3 x 5 x 17

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

Given numbers are 638, 214, 515, 255

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

Apply this formula for all numbers.

Step1:

LCM(638, 214) = 68266

GCD(638, 214) = ( 638 x 214 ) / 68266

= 638 / 214

= 638

Step2:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 638, 214, 515, 255 is 1
