Given numbers are 813, 249, 192, 256

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

Apply this formula for all numbers.

Step1:

LCM(813, 249) = 67479

GCD(813, 249) = ( 813 x 249 ) / 67479

= 813 / 249

= 813

Step2:

LCM(3, 192) = 192

GCD(3, 192) = ( 3 x 192 ) / 192

= 3 / 192

= 3

Step3:

LCM(3, 256) = 768

GCD(3, 256) = ( 3 x 256 ) / 768

= 3 / 256

= 3

So, Greatest Common Divisor of 813, 249, 192, 256 is 1
