Finding GCD of 78, 36, 12 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(78, 36) = 468

GCD(78, 36) = ( 78 x 36 ) / 468

GCD(78, 36) = 2808 / 468

GCD(78, 36) = 6


Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 12

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(6, 12) = 12

GCD(6, 12) = ( 6 x 12 ) / 12

GCD(6, 12) = 72 / 12

GCD(6, 12) = 6

GCD of 78, 36, 12 is 6
