Therefore, GCD of numbers 288, 621, 651, 958 is 1

Given Input Data is 288, 621, 651, 958

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

Prime Factorization of 288 is 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 958 is 2 x 479

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(288, 621) = 19872

GCD(288, 621) = ( 288 x 621 ) / 19872

GCD(288, 621) = 178848 / 19872

GCD(288, 621) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 651

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

LCM(9, 651) = 1953

GCD(9, 651) = ( 9 x 651 ) / 1953

GCD(9, 651) = 5859 / 1953

GCD(9, 651) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 958

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

LCM(3, 958) = 2874

GCD(3, 958) = ( 3 x 958 ) / 2874

GCD(3, 958) = 2874 / 2874

GCD(3, 958) = 1

GCD of 288, 621, 651, 958 is 1
