Finding GCD of 642, 780, 706 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, 780) = 83460

GCD(642, 780) = ( 642 x 780 ) / 83460

GCD(642, 780) = 500760 / 83460

GCD(642, 780) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 706

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(6, 706) = 2118

GCD(6, 706) = ( 6 x 706 ) / 2118

GCD(6, 706) = 4236 / 2118

GCD(6, 706) = 2

GCD of 642, 780, 706 is 2
