Given Input Data is 153, 391, 429, 964

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

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 391 is 17 x 23

Prime Factorization of 429 is 3 x 11 x 13

Prime Factorization of 964 is 2 x 2 x 241

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(153, 391) = 3519

GCD(153, 391) = ( 153 x 391 ) / 3519

GCD(153, 391) = 59823 / 3519

GCD(153, 391) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 429

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

LCM(17, 429) = 7293

GCD(17, 429) = ( 17 x 429 ) / 7293

GCD(17, 429) = 7293 / 7293

GCD(17, 429) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 964

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

LCM(1, 964) = 964

GCD(1, 964) = ( 1 x 964 ) / 964

GCD(1, 964) = 964 / 964

GCD(1, 964) = 1

GCD of 153, 391, 429, 964 is 1
