Finding GCD of 781, 385, 310 using Prime Factorization

Given Input Data is 781, 385, 310

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 781 is 11 x 71

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 310 is 2 x 5 x 31

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 781, 385, 310 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(781, 385) = 27335

GCD(781, 385) = ( 781 x 385 ) / 27335

GCD(781, 385) = 300685 / 27335

GCD(781, 385) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 310

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

LCM(11, 310) = 3410

GCD(11, 310) = ( 11 x 310 ) / 3410

GCD(11, 310) = 3410 / 3410

GCD(11, 310) = 1

GCD of 781, 385, 310 is 1
