Finding GCD of 26, 78, 84 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(26, 78) = 78
GCD(26, 78) = ( 26 x 78 ) / 78
GCD(26, 78) = 2028 / 78
GCD(26, 78) = 26
Step2:
Here we consider the GCD from the above i.e. 26 as first number and the next as 84
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(26, 84) = 1092
GCD(26, 84) = ( 26 x 84 ) / 1092
GCD(26, 84) = 2184 / 1092
GCD(26, 84) = 2
GCD of 26, 78, 84 is 2
