Given Input Data is 897, 447, 72, 700

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

Prime Factorization of 897 is 3 x 13 x 23

Prime Factorization of 447 is 3 x 149

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 700 is 2 x 2 x 5 x 5 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(897, 447) = 133653

GCD(897, 447) = ( 897 x 447 ) / 133653

GCD(897, 447) = 400959 / 133653

GCD(897, 447) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 72

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

LCM(3, 72) = 72

GCD(3, 72) = ( 3 x 72 ) / 72

GCD(3, 72) = 216 / 72

GCD(3, 72) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 700

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

LCM(3, 700) = 2100

GCD(3, 700) = ( 3 x 700 ) / 2100

GCD(3, 700) = 2100 / 2100

GCD(3, 700) = 1

GCD of 897, 447, 72, 700 is 1
