We found the divisors of 661, 207, 814, 474 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 661, 207, 814, 474 is 1.

Therefore, GCD of numbers 661, 207, 814, 474 is 1

Given Input Data is 661, 207, 814, 474

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

Prime Factorization of 661 is 661

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 814 is 2 x 11 x 37

Prime Factorization of 474 is 2 x 3 x 79

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, 207) = 136827

GCD(661, 207) = ( 661 x 207 ) / 136827

GCD(661, 207) = 136827 / 136827

GCD(661, 207) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 814

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

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

GCD(1, 814) = 814 / 814

GCD(1, 814) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 474

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

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

GCD(1, 474) = 474 / 474

GCD(1, 474) = 1

GCD of 661, 207, 814, 474 is 1
