Given Input Data is 282, 642, 564, 515

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

Prime Factorization of 282 is 2 x 3 x 47

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 564 is 2 x 2 x 3 x 47

Prime Factorization of 515 is 5 x 103

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(282, 642) = 30174

GCD(282, 642) = ( 282 x 642 ) / 30174

GCD(282, 642) = 181044 / 30174

GCD(282, 642) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 564

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

LCM(6, 564) = 564

GCD(6, 564) = ( 6 x 564 ) / 564

GCD(6, 564) = 3384 / 564

GCD(6, 564) = 6

Step3:

Here we consider the GCD from the above i.e. 6 as first number and the next as 515

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

LCM(6, 515) = 3090

GCD(6, 515) = ( 6 x 515 ) / 3090

GCD(6, 515) = 3090 / 3090

GCD(6, 515) = 1

GCD of 282, 642, 564, 515 is 1
