Given numbers are 503, 726, 109, 420

The list of prime factors of all numbers are

Prime factors of 503 are 503

Prime factors of 726 are 2 x 3 x 11 x 11

Prime factors of 109 are 109

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 503, 726, 109, 420

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

Apply this formula for all numbers.

Step1:

LCM(503, 726) = 365178

GCD(503, 726) = ( 503 x 726 ) / 365178

= 503 / 726

= 503

Step2:

LCM(1, 109) = 109

GCD(1, 109) = ( 1 x 109 ) / 109

= 1 / 109

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 503, 726, 109, 420 is 1
