Therefore, GCD of numbers 860, 325, 19, 521 is 1

Given Input Data is 860, 325, 19, 521

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

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 325 is 5 x 5 x 13

Prime Factorization of 19 is 19

Prime Factorization of 521 is 521

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(860, 325) = 55900

GCD(860, 325) = ( 860 x 325 ) / 55900

GCD(860, 325) = 279500 / 55900

GCD(860, 325) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 19

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

LCM(5, 19) = 95

GCD(5, 19) = ( 5 x 19 ) / 95

GCD(5, 19) = 95 / 95

GCD(5, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 521

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

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

GCD(1, 521) = 521 / 521

GCD(1, 521) = 1

GCD of 860, 325, 19, 521 is 1
