Given Input Data is 672, 807, 162, 821

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

Prime Factorization of 672 is 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime Factorization of 807 is 3 x 269

Prime Factorization of 162 is 2 x 3 x 3 x 3 x 3

Prime Factorization of 821 is 821

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(672, 807) = 180768

GCD(672, 807) = ( 672 x 807 ) / 180768

GCD(672, 807) = 542304 / 180768

GCD(672, 807) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 162

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

LCM(3, 162) = 162

GCD(3, 162) = ( 3 x 162 ) / 162

GCD(3, 162) = 486 / 162

GCD(3, 162) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 821

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

LCM(3, 821) = 2463

GCD(3, 821) = ( 3 x 821 ) / 2463

GCD(3, 821) = 2463 / 2463

GCD(3, 821) = 1

GCD of 672, 807, 162, 821 is 1
