Given numbers are 209, 868, 398, 877

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

Apply this formula for all numbers.

Step1:

LCM(209, 868) = 181412

GCD(209, 868) = ( 209 x 868 ) / 181412

= 209 / 868

= 209

Step2:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

Step3:

LCM(1, 877) = 877

GCD(1, 877) = ( 1 x 877 ) / 877

= 1 / 877

= 1

So, Greatest Common Divisor of 209, 868, 398, 877 is 1
