Therefore, GCD of numbers 670, 515, 669 is 1

Given Input Data is 670, 515, 669

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

Prime Factorization of 670 is 2 x 5 x 67

Prime Factorization of 515 is 5 x 103

Prime Factorization of 669 is 3 x 223

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(670, 515) = 69010

GCD(670, 515) = ( 670 x 515 ) / 69010

GCD(670, 515) = 345050 / 69010

GCD(670, 515) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 669

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

LCM(5, 669) = 3345

GCD(5, 669) = ( 5 x 669 ) / 3345

GCD(5, 669) = 3345 / 3345

GCD(5, 669) = 1

GCD of 670, 515, 669 is 1
