GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(801, 729) = 64881
GCD(801, 729) = ( 801 x 729 ) / 64881
= 801 / 729
= 801
Step2:
LCM(9, 153) = 153
GCD(9, 153) = ( 9 x 153 ) / 153
= 9 / 153
= 9
Step3:
LCM(9, 831) = 2493
GCD(9, 831) = ( 9 x 831 ) / 2493
= 9 / 831
= 9
So, Greatest Common Divisor of 801, 729, 153, 831 is 3
