Given numbers are 990, 721, 815, 366
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 721) = 713790
GCD(990, 721) = ( 990 x 721 ) / 713790
= 990 / 721
= 990
Step2:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
Step3:
LCM(1, 366) = 366
GCD(1, 366) = ( 1 x 366 ) / 366
= 1 / 366
= 1
So, Greatest Common Divisor of 990, 721, 815, 366 is 1
