Finding GCD of 939, 915, 688 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(939, 915) = 286395

GCD(939, 915) = ( 939 x 915 ) / 286395

GCD(939, 915) = 859185 / 286395

GCD(939, 915) = 3


Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 688

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

LCM(3, 688) = 2064

GCD(3, 688) = ( 3 x 688 ) / 2064

GCD(3, 688) = 2064 / 2064

GCD(3, 688) = 1

GCD of 939, 915, 688 is 1
