Finding GCD of 405, 940, 439 using LCM Formula
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(405, 940) = 76140
GCD(405, 940) = ( 405 x 940 ) / 76140
GCD(405, 940) = 380700 / 76140
GCD(405, 940) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 439
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 439) = 2195
GCD(5, 439) = ( 5 x 439 ) / 2195
GCD(5, 439) = 2195 / 2195
GCD(5, 439) = 1
GCD of 405, 940, 439 is 1
