Finding GCD of 555, 645, 440 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(555, 645) = 23865
GCD(555, 645) = ( 555 x 645 ) / 23865
GCD(555, 645) = 357975 / 23865
GCD(555, 645) = 15
Step2:
Here we consider the GCD from the above i.e. 15 as first number and the next as 440
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(15, 440) = 1320
GCD(15, 440) = ( 15 x 440 ) / 1320
GCD(15, 440) = 6600 / 1320
GCD(15, 440) = 5
GCD of 555, 645, 440 is 5
