Given numbers are 105, 720, 806, 729
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 720) = 5040
GCD(105, 720) = ( 105 x 720 ) / 5040
= 105 / 720
= 105
Step2:
LCM(15, 806) = 12090
GCD(15, 806) = ( 15 x 806 ) / 12090
= 15 / 806
= 15
Step3:
LCM(1, 729) = 729
GCD(1, 729) = ( 1 x 729 ) / 729
= 1 / 729
= 1
So, Greatest Common Divisor of 105, 720, 806, 729 is 1
