Therefore, GCD of numbers 49, 973, 390, 924 is 1

Given Input Data is 49, 973, 390, 924

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

Prime Factorization of 49 is 7 x 7

Prime Factorization of 973 is 7 x 139

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

Prime Factorization of 924 is 2 x 2 x 3 x 7 x 11

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(49, 973) = 6811

GCD(49, 973) = ( 49 x 973 ) / 6811

GCD(49, 973) = 47677 / 6811

GCD(49, 973) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 390

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

LCM(7, 390) = 2730

GCD(7, 390) = ( 7 x 390 ) / 2730

GCD(7, 390) = 2730 / 2730

GCD(7, 390) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 924

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

LCM(1, 924) = 924

GCD(1, 924) = ( 1 x 924 ) / 924

GCD(1, 924) = 924 / 924

GCD(1, 924) = 1

GCD of 49, 973, 390, 924 is 1
