Finding GCD of 436, 289, 68 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(436, 289) = 126004
GCD(436, 289) = ( 436 x 289 ) / 126004
GCD(436, 289) = 126004 / 126004
GCD(436, 289) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 68
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
GCD(1, 68) = 68 / 68
GCD(1, 68) = 1
GCD of 436, 289, 68 is 1
