GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(729, 805) = 586845
GCD(729, 805) = ( 729 x 805 ) / 586845
= 729 / 805
= 729
Step2:
LCM(1, 990) = 990
GCD(1, 990) = ( 1 x 990 ) / 990
= 1 / 990
= 1
Step3:
LCM(1, 222) = 222
GCD(1, 222) = ( 1 x 222 ) / 222
= 1 / 222
= 1
So, Greatest Common Divisor of 729, 805, 990, 222 is 1
