Given numbers are 819, 153, 217, 323

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

Apply this formula for all numbers.

Step1:

LCM(819, 153) = 13923

GCD(819, 153) = ( 819 x 153 ) / 13923

= 819 / 153

= 819

Step2:

LCM(9, 217) = 1953

GCD(9, 217) = ( 9 x 217 ) / 1953

= 9 / 217

= 9

Step3:

LCM(1, 323) = 323

GCD(1, 323) = ( 1 x 323 ) / 323

= 1 / 323

= 1

So, Greatest Common Divisor of 819, 153, 217, 323 is 1
