Therefore, GCD of numbers 373, 645, 51, 491 is 1

Given Input Data is 373, 645, 51, 491

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

Prime Factorization of 373 is 373

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 51 is 3 x 17

Prime Factorization of 491 is 491

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(373, 645) = 240585

GCD(373, 645) = ( 373 x 645 ) / 240585

GCD(373, 645) = 240585 / 240585

GCD(373, 645) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 51

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

LCM(1, 51) = 51

GCD(1, 51) = ( 1 x 51 ) / 51

GCD(1, 51) = 51 / 51

GCD(1, 51) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 491

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

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

GCD(1, 491) = 491 / 491

GCD(1, 491) = 1

GCD of 373, 645, 51, 491 is 1
