Finding GCD of 651, 840, 636 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(651, 840) = 26040
GCD(651, 840) = ( 651 x 840 ) / 26040
GCD(651, 840) = 546840 / 26040
GCD(651, 840) = 21
Step2:
Here we consider the GCD from the above i.e. 21 as first number and the next as 636
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(21, 636) = 4452
GCD(21, 636) = ( 21 x 636 ) / 4452
GCD(21, 636) = 13356 / 4452
GCD(21, 636) = 3
GCD of 651, 840, 636 is 3
