Given numbers are 503, 687, 648, 905

The list of prime factors of all numbers are

Prime factors of 503 are 503

Prime factors of 687 are 3 x 229

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

Prime factors of 905 are 5 x 181

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

Given numbers are 503, 687, 648, 905

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

Apply this formula for all numbers.

Step1:

LCM(503, 687) = 345561

GCD(503, 687) = ( 503 x 687 ) / 345561

= 503 / 687

= 503

Step2:

LCM(1, 648) = 648

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

= 1 / 648

= 1

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 503, 687, 648, 905 is 1
