Given numbers are 243, 306, 738, 403
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 306) = 8262
GCD(243, 306) = ( 243 x 306 ) / 8262
= 243 / 306
= 243
Step2:
LCM(9, 738) = 738
GCD(9, 738) = ( 9 x 738 ) / 738
= 9 / 738
= 9
Step3:
LCM(9, 403) = 3627
GCD(9, 403) = ( 9 x 403 ) / 3627
= 9 / 403
= 9
So, Greatest Common Divisor of 243, 306, 738, 403 is 1
