Finding GCD of 405, 330, 258 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(405, 330) = 8910
GCD(405, 330) = ( 405 x 330 ) / 8910
GCD(405, 330) = 133650 / 8910
GCD(405, 330) = 15
Step2:
Here we consider the GCD from the above i.e. 15 as first number and the next as 258
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(15, 258) = 1290
GCD(15, 258) = ( 15 x 258 ) / 1290
GCD(15, 258) = 3870 / 1290
GCD(15, 258) = 3
GCD of 405, 330, 258 is 3
