Therefore, GCD of numbers 447, 645, 625, 370 is 1

Given Input Data is 447, 645, 625, 370

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

Prime Factorization of 447 is 3 x 149

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 625 is 5 x 5 x 5 x 5

Prime Factorization of 370 is 2 x 5 x 37

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(447, 645) = 96105

GCD(447, 645) = ( 447 x 645 ) / 96105

GCD(447, 645) = 288315 / 96105

GCD(447, 645) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 625

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

LCM(3, 625) = 1875

GCD(3, 625) = ( 3 x 625 ) / 1875

GCD(3, 625) = 1875 / 1875

GCD(3, 625) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 370

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

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

GCD(1, 370) = 370 / 370

GCD(1, 370) = 1

GCD of 447, 645, 625, 370 is 1
