Given numbers are 243, 882, 390, 439

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

Apply this formula for all numbers.

Step1:

LCM(243, 882) = 23814

GCD(243, 882) = ( 243 x 882 ) / 23814

= 243 / 882

= 243

Step2:

LCM(9, 390) = 1170

GCD(9, 390) = ( 9 x 390 ) / 1170

= 9 / 390

= 9

Step3:

LCM(3, 439) = 1317

GCD(3, 439) = ( 3 x 439 ) / 1317

= 3 / 439

= 3

So, Greatest Common Divisor of 243, 882, 390, 439 is 1
