Therefore, GCD of numbers 645, 410, 62, 225 is 1

Given Input Data is 645, 410, 62, 225

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

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 410 is 2 x 5 x 41

Prime Factorization of 62 is 2 x 31

Prime Factorization of 225 is 3 x 3 x 5 x 5

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

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(645, 410) = 52890

GCD(645, 410) = ( 645 x 410 ) / 52890

GCD(645, 410) = 264450 / 52890

GCD(645, 410) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 62

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

LCM(5, 62) = 310

GCD(5, 62) = ( 5 x 62 ) / 310

GCD(5, 62) = 310 / 310

GCD(5, 62) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 225

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

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

GCD(1, 225) = 225 / 225

GCD(1, 225) = 1

GCD of 645, 410, 62, 225 is 1
