Finding GCD of 788, 136, 821 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(788, 136) = 26792

GCD(788, 136) = ( 788 x 136 ) / 26792

GCD(788, 136) = 107168 / 26792

GCD(788, 136) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 821

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

LCM(4, 821) = 3284

GCD(4, 821) = ( 4 x 821 ) / 3284

GCD(4, 821) = 3284 / 3284

GCD(4, 821) = 1

GCD of 788, 136, 821 is 1
