We found the divisors of 691, 652, 662, 666 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 691, 652, 662, 666 is 1.

Therefore, GCD of numbers 691, 652, 662, 666 is 1

Given Input Data is 691, 652, 662, 666

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

Prime Factorization of 691 is 691

Prime Factorization of 652 is 2 x 2 x 163

Prime Factorization of 662 is 2 x 331

Prime Factorization of 666 is 2 x 3 x 3 x 37

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, 652) = 450532

GCD(691, 652) = ( 691 x 652 ) / 450532

GCD(691, 652) = 450532 / 450532

GCD(691, 652) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 662

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

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

GCD(1, 662) = 662 / 662

GCD(1, 662) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 666

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

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

GCD(1, 666) = 666 / 666

GCD(1, 666) = 1

GCD of 691, 652, 662, 666 is 1
