Finding GCD of 655, 245, 828 using Prime Factorization

Given Input Data is 655, 245, 828

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

Prime Factorization of 655 is 5 x 131

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 828 is 2 x 2 x 3 x 3 x 23

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

Finding GCD of 655, 245, 828 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(655, 245) = 32095

GCD(655, 245) = ( 655 x 245 ) / 32095

GCD(655, 245) = 160475 / 32095

GCD(655, 245) = 5


Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 828

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

LCM(5, 828) = 4140

GCD(5, 828) = ( 5 x 828 ) / 4140

GCD(5, 828) = 4140 / 4140

GCD(5, 828) = 1

GCD of 655, 245, 828 is 1
