Finding GCD of 788, 282, 405 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(788, 282) = 111108
GCD(788, 282) = ( 788 x 282 ) / 111108
GCD(788, 282) = 222216 / 111108
GCD(788, 282) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 405
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 405) = 810
GCD(2, 405) = ( 2 x 405 ) / 810
GCD(2, 405) = 810 / 810
GCD(2, 405) = 1
GCD of 788, 282, 405 is 1
