Finding GCD of 56, 20, 34 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(56, 20) = 280

GCD(56, 20) = ( 56 x 20 ) / 280

GCD(56, 20) = 1120 / 280

GCD(56, 20) = 4


Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 34

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

LCM(4, 34) = 68

GCD(4, 34) = ( 4 x 34 ) / 68

GCD(4, 34) = 136 / 68

GCD(4, 34) = 2

GCD of 56, 20, 34 is 2
