Finding GCD of 48, 18, 28 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(48, 18) = 144
GCD(48, 18) = ( 48 x 18 ) / 144
GCD(48, 18) = 864 / 144
GCD(48, 18) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 28
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 28) = 84
GCD(6, 28) = ( 6 x 28 ) / 84
GCD(6, 28) = 168 / 84
GCD(6, 28) = 2
GCD of 48, 18, 28 is 2
