GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(711, 981) = 77499
GCD(711, 981) = ( 711 x 981 ) / 77499
= 711 / 981
= 711
Step2:
LCM(9, 405) = 405
GCD(9, 405) = ( 9 x 405 ) / 405
= 9 / 405
= 9
Step3:
LCM(9, 243) = 243
GCD(9, 243) = ( 9 x 243 ) / 243
= 9 / 243
= 9
So, Greatest Common Divisor of 711, 981, 405, 243 is 9
