Finding GCD of 261, 159, 79 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(261, 159) = 13833

GCD(261, 159) = ( 261 x 159 ) / 13833

GCD(261, 159) = 41499 / 13833

GCD(261, 159) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 79

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

LCM(3, 79) = 237

GCD(3, 79) = ( 3 x 79 ) / 237

GCD(3, 79) = 237 / 237

GCD(3, 79) = 1

GCD of 261, 159, 79 is 1
