Finding GCD of 620, 645, 53 using Prime Factorization

Given Input Data is 620, 645, 53

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

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 53 is 53

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

Finding GCD of 620, 645, 53 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(620, 645) = 79980

GCD(620, 645) = ( 620 x 645 ) / 79980

GCD(620, 645) = 399900 / 79980

GCD(620, 645) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 53

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

LCM(5, 53) = 265

GCD(5, 53) = ( 5 x 53 ) / 265

GCD(5, 53) = 265 / 265

GCD(5, 53) = 1

GCD of 620, 645, 53 is 1
