Finding GCD of 642, 810, 669 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(642, 810) = 86670
GCD(642, 810) = ( 642 x 810 ) / 86670
GCD(642, 810) = 520020 / 86670
GCD(642, 810) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 669
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 669) = 1338
GCD(6, 669) = ( 6 x 669 ) / 1338
GCD(6, 669) = 4014 / 1338
GCD(6, 669) = 3
GCD of 642, 810, 669 is 3
