Finding GCD of 868, 819, 56 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(868, 819) = 101556
GCD(868, 819) = ( 868 x 819 ) / 101556
GCD(868, 819) = 710892 / 101556
GCD(868, 819) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 56
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 56) = 56
GCD(7, 56) = ( 7 x 56 ) / 56
GCD(7, 56) = 392 / 56
GCD(7, 56) = 7
GCD of 868, 819, 56 is 7
