Given numbers are 217, 387, 504, 503

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 387 are 3 x 3 x 43

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 503 are 503

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

Given numbers are 217, 387, 504, 503

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

Apply this formula for all numbers.

Step1:

LCM(217, 387) = 83979

GCD(217, 387) = ( 217 x 387 ) / 83979

= 217 / 387

= 217

Step2:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

Step3:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1

So, Greatest Common Divisor of 217, 387, 504, 503 is 1
