Therefore, GCD of numbers 551, 923, 451, 649 is 1

Given Input Data is 551, 923, 451, 649

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

Prime Factorization of 551 is 19 x 29

Prime Factorization of 923 is 13 x 71

Prime Factorization of 451 is 11 x 41

Prime Factorization of 649 is 11 x 59

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, 923) = 508573

GCD(551, 923) = ( 551 x 923 ) / 508573

GCD(551, 923) = 508573 / 508573

GCD(551, 923) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 451

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

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

GCD(1, 451) = 451 / 451

GCD(1, 451) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 649

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

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

GCD(1, 649) = 649 / 649

GCD(1, 649) = 1

GCD of 551, 923, 451, 649 is 1
