Finding GCD of 545, 245, 243 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(545, 245) = 26705
GCD(545, 245) = ( 545 x 245 ) / 26705
GCD(545, 245) = 133525 / 26705
GCD(545, 245) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 243
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 243) = 1215
GCD(5, 243) = ( 5 x 243 ) / 1215
GCD(5, 243) = 1215 / 1215
GCD(5, 243) = 1
GCD of 545, 245, 243 is 1
