Finding GCD of 84, 70, 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(84, 70) = 420
GCD(84, 70) = ( 84 x 70 ) / 420
GCD(84, 70) = 5880 / 420
GCD(84, 70) = 14
Step2:
Here we consider the GCD from the above i.e. 14 as first number and the next as 79
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(14, 79) = 1106
GCD(14, 79) = ( 14 x 79 ) / 1106
GCD(14, 79) = 1106 / 1106
GCD(14, 79) = 1
GCD of 84, 70, 79 is 1
