Finding GCD of 855, 873, 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(855, 873) = 82935
GCD(855, 873) = ( 855 x 873 ) / 82935
GCD(855, 873) = 746415 / 82935
GCD(855, 873) = 9
Step2:
Here we consider the GCD from the above i.e. 9 as first number and the next as 28
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(9, 28) = 252
GCD(9, 28) = ( 9 x 28 ) / 252
GCD(9, 28) = 252 / 252
GCD(9, 28) = 1
GCD of 855, 873, 28 is 1
