Given numbers are 727, 503, 638, 420

The list of prime factors of all numbers are

Prime factors of 727 are 727

Prime factors of 503 are 503

Prime factors of 638 are 2 x 11 x 29

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 727, 503, 638, 420

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

Apply this formula for all numbers.

Step1:

LCM(727, 503) = 365681

GCD(727, 503) = ( 727 x 503 ) / 365681

= 727 / 503

= 727

Step2:

LCM(1, 638) = 638

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

= 1 / 638

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 727, 503, 638, 420 is 1
