We found the divisors of 490, 710, 491, 577 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 490, 710, 491, 577 is 1.

Therefore, GCD of numbers 490, 710, 491, 577 is 1

Given Input Data is 490, 710, 491, 577

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

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 710 is 2 x 5 x 71

Prime Factorization of 491 is 491

Prime Factorization of 577 is 577

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(490, 710) = 34790

GCD(490, 710) = ( 490 x 710 ) / 34790

GCD(490, 710) = 347900 / 34790

GCD(490, 710) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 491

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

LCM(10, 491) = 4910

GCD(10, 491) = ( 10 x 491 ) / 4910

GCD(10, 491) = 4910 / 4910

GCD(10, 491) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 577

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

LCM(1, 577) = 577

GCD(1, 577) = ( 1 x 577 ) / 577

GCD(1, 577) = 577 / 577

GCD(1, 577) = 1

GCD of 490, 710, 491, 577 is 1
