Given numbers are 638, 503, 597, 780

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 503 are 503

Prime factors of 597 are 3 x 199

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 638, 503, 597, 780

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

Apply this formula for all numbers.

Step1:

LCM(638, 503) = 320914

GCD(638, 503) = ( 638 x 503 ) / 320914

= 638 / 503

= 638

Step2:

LCM(1, 597) = 597

GCD(1, 597) = ( 1 x 597 ) / 597

= 1 / 597

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 638, 503, 597, 780 is 1
