Finding GCD of 225, 870, 79 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(225, 870) = 13050
GCD(225, 870) = ( 225 x 870 ) / 13050
GCD(225, 870) = 195750 / 13050
GCD(225, 870) = 15
Step2:
Here we consider the GCD from the above i.e. 15 as first number and the next as 79
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(15, 79) = 1185
GCD(15, 79) = ( 15 x 79 ) / 1185
GCD(15, 79) = 1185 / 1185
GCD(15, 79) = 1
GCD of 225, 870, 79 is 1
