Therefore, GCD of numbers 661, 841, 671 is 1

Given Input Data is 661, 841, 671

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

Prime Factorization of 661 is 661

Prime Factorization of 841 is 29 x 29

Prime Factorization of 671 is 11 x 61

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(661, 841) = 555901

GCD(661, 841) = ( 661 x 841 ) / 555901

GCD(661, 841) = 555901 / 555901

GCD(661, 841) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 671

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

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

GCD(1, 671) = 671 / 671

GCD(1, 671) = 1

GCD of 661, 841, 671 is 1
