GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 840) = 840
GCD(105, 840) = ( 105 x 840 ) / 840
= 105 / 840
= 105
Step2:
LCM(105, 729) = 25515
GCD(105, 729) = ( 105 x 729 ) / 25515
= 105 / 729
= 105
Step3:
LCM(3, 443) = 1329
GCD(3, 443) = ( 3 x 443 ) / 1329
= 3 / 443
= 3
So, Greatest Common Divisor of 105, 840, 729, 443 is 1
