Finding GCD of 213, 315, 649 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(213, 315) = 22365
GCD(213, 315) = ( 213 x 315 ) / 22365
GCD(213, 315) = 67095 / 22365
GCD(213, 315) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 649
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 649) = 1947
GCD(3, 649) = ( 3 x 649 ) / 1947
GCD(3, 649) = 1947 / 1947
GCD(3, 649) = 1
GCD of 213, 315, 649 is 1
