Finding GCD of 415, 990, 649 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(415, 990) = 82170
GCD(415, 990) = ( 415 x 990 ) / 82170
GCD(415, 990) = 410850 / 82170
GCD(415, 990) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 649
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 649) = 3245
GCD(5, 649) = ( 5 x 649 ) / 3245
GCD(5, 649) = 3245 / 3245
GCD(5, 649) = 1
GCD of 415, 990, 649 is 1
