Finding GCD of 68, 84, 38 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(68, 84) = 1428
GCD(68, 84) = ( 68 x 84 ) / 1428
GCD(68, 84) = 5712 / 1428
GCD(68, 84) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 38
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 38) = 76
GCD(4, 38) = ( 4 x 38 ) / 76
GCD(4, 38) = 152 / 76
GCD(4, 38) = 2
GCD of 68, 84, 38 is 2
