Finding GCD of 40, 68, 86 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(40, 68) = 680
GCD(40, 68) = ( 40 x 68 ) / 680
GCD(40, 68) = 2720 / 680
GCD(40, 68) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 86
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 86) = 172
GCD(4, 86) = ( 4 x 86 ) / 172
GCD(4, 86) = 344 / 172
GCD(4, 86) = 2
GCD of 40, 68, 86 is 2
