Given numbers are 207, 228, 680, 819

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

Apply this formula for all numbers.

Step1:

LCM(207, 228) = 15732

GCD(207, 228) = ( 207 x 228 ) / 15732

= 207 / 228

= 207

Step2:

LCM(3, 680) = 2040

GCD(3, 680) = ( 3 x 680 ) / 2040

= 3 / 680

= 3

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 207, 228, 680, 819 is 1
