Finding GCD of 378, 645, 515 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(378, 645) = 81270
GCD(378, 645) = ( 378 x 645 ) / 81270
GCD(378, 645) = 243810 / 81270
GCD(378, 645) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 515
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 515) = 1545
GCD(3, 515) = ( 3 x 515 ) / 1545
GCD(3, 515) = 1545 / 1545
GCD(3, 515) = 1
GCD of 378, 645, 515 is 1
