Given Input Data is 451, 913, 390, 913

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

Prime Factorization of 451 is 11 x 41

Prime Factorization of 913 is 11 x 83

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

Prime Factorization of 913 is 11 x 83

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(451, 913) = 37433

GCD(451, 913) = ( 451 x 913 ) / 37433

GCD(451, 913) = 411763 / 37433

GCD(451, 913) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 390

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

LCM(11, 390) = 4290

GCD(11, 390) = ( 11 x 390 ) / 4290

GCD(11, 390) = 4290 / 4290

GCD(11, 390) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 913

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

LCM(1, 913) = 913

GCD(1, 913) = ( 1 x 913 ) / 913

GCD(1, 913) = 913 / 913

GCD(1, 913) = 1

GCD of 451, 913, 390, 913 is 1
