Therefore, GCD of numbers 105, 921, 36, 320 is 1

Given Input Data is 105, 921, 36, 320

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

Prime Factorization of 105 is 3 x 5 x 7

Prime Factorization of 921 is 3 x 307

Prime Factorization of 36 is 2 x 2 x 3 x 3

Prime Factorization of 320 is 2 x 2 x 2 x 2 x 2 x 2 x 5

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(105, 921) = 32235

GCD(105, 921) = ( 105 x 921 ) / 32235

GCD(105, 921) = 96705 / 32235

GCD(105, 921) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 36

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

LCM(3, 36) = 36

GCD(3, 36) = ( 3 x 36 ) / 36

GCD(3, 36) = 108 / 36

GCD(3, 36) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 320

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

LCM(3, 320) = 960

GCD(3, 320) = ( 3 x 320 ) / 960

GCD(3, 320) = 960 / 960

GCD(3, 320) = 1

GCD of 105, 921, 36, 320 is 1
