Given numbers are 638, 615, 483, 872

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 615 are 3 x 5 x 41

Prime factors of 483 are 3 x 7 x 23

Prime factors of 872 are 2 x 2 x 2 x 109

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

Given numbers are 638, 615, 483, 872

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

Apply this formula for all numbers.

Step1:

LCM(638, 615) = 392370

GCD(638, 615) = ( 638 x 615 ) / 392370

= 638 / 615

= 638

Step2:

LCM(1, 483) = 483

GCD(1, 483) = ( 1 x 483 ) / 483

= 1 / 483

= 1

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 638, 615, 483, 872 is 1
