Therefore, GCD of numbers 21, 625, 897, 881 is 1

Given Input Data is 21, 625, 897, 881

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

Prime Factorization of 21 is 3 x 7

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

Prime Factorization of 897 is 3 x 13 x 23

Prime Factorization of 881 is 881

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(21, 625) = 13125

GCD(21, 625) = ( 21 x 625 ) / 13125

GCD(21, 625) = 13125 / 13125

GCD(21, 625) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 897

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

LCM(1, 897) = 897

GCD(1, 897) = ( 1 x 897 ) / 897

GCD(1, 897) = 897 / 897

GCD(1, 897) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 881

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

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

GCD(1, 881) = 881 / 881

GCD(1, 881) = 1

GCD of 21, 625, 897, 881 is 1
