GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(729, 990) = 80190
GCD(729, 990) = ( 729 x 990 ) / 80190
= 729 / 990
= 729
Step2:
LCM(9, 869) = 7821
GCD(9, 869) = ( 9 x 869 ) / 7821
= 9 / 869
= 9
Step3:
LCM(1, 158) = 158
GCD(1, 158) = ( 1 x 158 ) / 158
= 1 / 158
= 1
So, Greatest Common Divisor of 729, 990, 869, 158 is 1
