Greatest Common Divisior

We found the divisors of 679, 657, 619, 100 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 679, 657, 619, 100 is 1.

Therefore, GCD of numbers 679, 657, 619, 100 is 1

Given Input Data is 679, 657, 619, 100

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

Prime Factorization of 679 is 7 x 97

Prime Factorization of 657 is 3 x 3 x 73

Prime Factorization of 619 is 619

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(679, 657) = 446103

GCD(679, 657) = ( 679 x 657 ) / 446103

GCD(679, 657) = 446103 / 446103

GCD(679, 657) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 619

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

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

GCD(1, 619) = 619 / 619

GCD(1, 619) = 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 679, 657, 619, 100 is 1
