Given numbers are 508, 203, 864, 638

The list of prime factors of all numbers are

Prime factors of 508 are 2 x 2 x 127

Prime factors of 203 are 7 x 29

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 508, 203, 864, 638

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

Apply this formula for all numbers.

Step1:

LCM(508, 203) = 103124

GCD(508, 203) = ( 508 x 203 ) / 103124

= 508 / 203

= 508

Step2:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 508, 203, 864, 638 is 1
