Finding GCD of 385, 161, 817 using Prime Factorization

Given Input Data is 385, 161, 817

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

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 161 is 7 x 23

Prime Factorization of 817 is 19 x 43

Finding GCD of 385, 161, 817 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(385, 161) = 8855

GCD(385, 161) = ( 385 x 161 ) / 8855

GCD(385, 161) = 61985 / 8855

GCD(385, 161) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 817

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

LCM(7, 817) = 5719

GCD(7, 817) = ( 7 x 817 ) / 5719

GCD(7, 817) = 5719 / 5719

GCD(7, 817) = 1

GCD of 385, 161, 817 is 1
