We found the divisors of 100, 681, 56, 729 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 100, 681, 56, 729 is 1.

Therefore, GCD of numbers 100, 681, 56, 729 is 1

Given Input Data is 100, 681, 56, 729

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

Prime Factorization of 100 is 2 x 2 x 5 x 5

Prime Factorization of 681 is 3 x 227

Prime Factorization of 56 is 2 x 2 x 2 x 7

Prime Factorization of 729 is 3 x 3 x 3 x 3 x 3 x 3

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(100, 681) = 68100

GCD(100, 681) = ( 100 x 681 ) / 68100

GCD(100, 681) = 68100 / 68100

GCD(100, 681) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 56

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

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

GCD(1, 56) = 56 / 56

GCD(1, 56) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 729

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

LCM(1, 729) = 729

GCD(1, 729) = ( 1 x 729 ) / 729

GCD(1, 729) = 729 / 729

GCD(1, 729) = 1

GCD of 100, 681, 56, 729 is 1
