Given numbers are 503, 738, 648, 409

The list of prime factors of all numbers are

Prime factors of 503 are 503

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 409 are 409

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

Given numbers are 503, 738, 648, 409

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

Apply this formula for all numbers.

Step1:

LCM(503, 738) = 371214

GCD(503, 738) = ( 503 x 738 ) / 371214

= 503 / 738

= 503

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

So, Greatest Common Divisor of 503, 738, 648, 409 is 1
