Given numbers are 203, 404, 781, 680

The list of prime factors of all numbers are

Prime factors of 203 are 7 x 29

Prime factors of 404 are 2 x 2 x 101

Prime factors of 781 are 11 x 71

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 203, 404, 781, 680

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

Apply this formula for all numbers.

Step1:

LCM(203, 404) = 82012

GCD(203, 404) = ( 203 x 404 ) / 82012

= 203 / 404

= 203

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 203, 404, 781, 680 is 1
