Given Input Data is 570, 715, 74, 378

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

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 74 is 2 x 37

Prime Factorization of 378 is 2 x 3 x 3 x 3 x 7

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(570, 715) = 81510

GCD(570, 715) = ( 570 x 715 ) / 81510

GCD(570, 715) = 407550 / 81510

GCD(570, 715) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 74

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

LCM(5, 74) = 370

GCD(5, 74) = ( 5 x 74 ) / 370

GCD(5, 74) = 370 / 370

GCD(5, 74) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 378

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

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

GCD(1, 378) = 378 / 378

GCD(1, 378) = 1

GCD of 570, 715, 74, 378 is 1
