GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 256) = 105216
GCD(822, 256) = ( 822 x 256 ) / 105216
= 822 / 256
= 822
Step2:
LCM(2, 366) = 366
GCD(2, 366) = ( 2 x 366 ) / 366
= 2 / 366
= 2
Step3:
LCM(2, 990) = 990
GCD(2, 990) = ( 2 x 990 ) / 990
= 2 / 990
= 2
So, Greatest Common Divisor of 822, 256, 366, 990 is 2
