Finding GCD of 46, 42, 80 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(46, 42) = 966
GCD(46, 42) = ( 46 x 42 ) / 966
GCD(46, 42) = 1932 / 966
GCD(46, 42) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 80
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 80) = 80
GCD(2, 80) = ( 2 x 80 ) / 80
GCD(2, 80) = 160 / 80
GCD(2, 80) = 2
GCD of 46, 42, 80 is 2
