We found the divisors of 991, 326, 70, 605 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 991, 326, 70, 605 is 1.

Therefore, GCD of numbers 991, 326, 70, 605 is 1

Given Input Data is 991, 326, 70, 605

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

Prime Factorization of 991 is 991

Prime Factorization of 326 is 2 x 163

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 605 is 5 x 11 x 11

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(991, 326) = 323066

GCD(991, 326) = ( 991 x 326 ) / 323066

GCD(991, 326) = 323066 / 323066

GCD(991, 326) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 70

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

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

GCD(1, 70) = 70 / 70

GCD(1, 70) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 605

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

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

GCD(1, 605) = 605 / 605

GCD(1, 605) = 1

GCD of 991, 326, 70, 605 is 1
