Given Input Data is 551, 390, 56, 951

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

Prime Factorization of 551 is 19 x 29

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 56 is 2 x 2 x 2 x 7

Prime Factorization of 951 is 3 x 317

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(551, 390) = 214890

GCD(551, 390) = ( 551 x 390 ) / 214890

GCD(551, 390) = 214890 / 214890

GCD(551, 390) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 56

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

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

GCD(1, 56) = 56 / 56

GCD(1, 56) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 951

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

LCM(1, 951) = 951

GCD(1, 951) = ( 1 x 951 ) / 951

GCD(1, 951) = 951 / 951

GCD(1, 951) = 1

GCD of 551, 390, 56, 951 is 1
