Given numbers are 638, 904, 85, 500

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 904 are 2 x 2 x 2 x 113

Prime factors of 85 are 5 x 17

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

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

Given numbers are 638, 904, 85, 500

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

Apply this formula for all numbers.

Step1:

LCM(638, 904) = 288376

GCD(638, 904) = ( 638 x 904 ) / 288376

= 638 / 904

= 638

Step2:

LCM(2, 85) = 170

GCD(2, 85) = ( 2 x 85 ) / 170

= 2 / 85

= 2

Step3:

LCM(1, 500) = 500

GCD(1, 500) = ( 1 x 500 ) / 500

= 1 / 500

= 1

So, Greatest Common Divisor of 638, 904, 85, 500 is 1
