We found the divisors of 803, 247, 717, 100 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 803, 247, 717, 100 is 1.

Therefore, GCD of numbers 803, 247, 717, 100 is 1

Given Input Data is 803, 247, 717, 100

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

Prime Factorization of 803 is 11 x 73

Prime Factorization of 247 is 13 x 19

Prime Factorization of 717 is 3 x 239

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

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(803, 247) = 198341

GCD(803, 247) = ( 803 x 247 ) / 198341

GCD(803, 247) = 198341 / 198341

GCD(803, 247) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 717

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

LCM(1, 717) = 717

GCD(1, 717) = ( 1 x 717 ) / 717

GCD(1, 717) = 717 / 717

GCD(1, 717) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 100

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

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

GCD(1, 100) = 100 / 100

GCD(1, 100) = 1

GCD of 803, 247, 717, 100 is 1
