Finding GCD of 402, 147, 197 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(402, 147) = 19698
GCD(402, 147) = ( 402 x 147 ) / 19698
GCD(402, 147) = 59094 / 19698
GCD(402, 147) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 197
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 197) = 591
GCD(3, 197) = ( 3 x 197 ) / 591
GCD(3, 197) = 591 / 591
GCD(3, 197) = 1
GCD of 402, 147, 197 is 1
