Therefore, GCD of numbers 940, 455, 239, 669 is 1

Given Input Data is 940, 455, 239, 669

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

Prime Factorization of 940 is 2 x 2 x 5 x 47

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 239 is 239

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(940, 455) = 85540

GCD(940, 455) = ( 940 x 455 ) / 85540

GCD(940, 455) = 427700 / 85540

GCD(940, 455) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 239

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

LCM(5, 239) = 1195

GCD(5, 239) = ( 5 x 239 ) / 1195

GCD(5, 239) = 1195 / 1195

GCD(5, 239) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 669

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

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

GCD(1, 669) = 669 / 669

GCD(1, 669) = 1

GCD of 940, 455, 239, 669 is 1
