Therefore, GCD of numbers 646, 152, 951, 622 is 1

Given Input Data is 646, 152, 951, 622

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

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 152 is 2 x 2 x 2 x 19

Prime Factorization of 951 is 3 x 317

Prime Factorization of 622 is 2 x 311

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(646, 152) = 2584

GCD(646, 152) = ( 646 x 152 ) / 2584

GCD(646, 152) = 98192 / 2584

GCD(646, 152) = 38

Step2:

Here we consider the GCD from the above i.e. 38 as first number and the next as 951

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

LCM(38, 951) = 36138

GCD(38, 951) = ( 38 x 951 ) / 36138

GCD(38, 951) = 36138 / 36138

GCD(38, 951) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 622

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

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

GCD(1, 622) = 622 / 622

GCD(1, 622) = 1

GCD of 646, 152, 951, 622 is 1
