Given numbers are 203, 394, 187, 720

The list of prime factors of all numbers are

Prime factors of 203 are 7 x 29

Prime factors of 394 are 2 x 197

Prime factors of 187 are 11 x 17

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 203, 394, 187, 720

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

Apply this formula for all numbers.

Step1:

LCM(203, 394) = 79982

GCD(203, 394) = ( 203 x 394 ) / 79982

= 203 / 394

= 203

Step2:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 203, 394, 187, 720 is 1
