GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(818, 497) = 406546
GCD(818, 497) = ( 818 x 497 ) / 406546
= 818 / 497
= 818
Step2:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
Step3:
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
= 1 / 243
= 1
So, Greatest Common Divisor of 818, 497, 409, 243 is 1
