Given numbers are 209, 872, 813, 251

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

Apply this formula for all numbers.

Step1:

LCM(209, 872) = 182248

GCD(209, 872) = ( 209 x 872 ) / 182248

= 209 / 872

= 209

Step2:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

Step3:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

So, Greatest Common Divisor of 209, 872, 813, 251 is 1
