We found the divisors of 691, 521, 400 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 691, 521, 400 is 1.

Therefore, GCD of numbers 691, 521, 400 is 1

Given Input Data is 691, 521, 400

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

Prime Factorization of 691 is 691

Prime Factorization of 521 is 521

Prime Factorization of 400 is 2 x 2 x 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(691, 521) = 360011

GCD(691, 521) = ( 691 x 521 ) / 360011

GCD(691, 521) = 360011 / 360011

GCD(691, 521) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 400

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

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

GCD(1, 400) = 400 / 400

GCD(1, 400) = 1

GCD of 691, 521, 400 is 1
