Therefore, GCD of numbers 860, 490, 13, 629 is 1

Given Input Data is 860, 490, 13, 629

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 490 is 2 x 5 x 7 x 7

Prime Factorization of 13 is 13

Prime Factorization of 629 is 17 x 37

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, 490) = 42140

GCD(860, 490) = ( 860 x 490 ) / 42140

GCD(860, 490) = 421400 / 42140

GCD(860, 490) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 13

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

LCM(10, 13) = 130

GCD(10, 13) = ( 10 x 13 ) / 130

GCD(10, 13) = 130 / 130

GCD(10, 13) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 629

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

LCM(1, 629) = 629

GCD(1, 629) = ( 1 x 629 ) / 629

GCD(1, 629) = 629 / 629

GCD(1, 629) = 1

GCD of 860, 490, 13, 629 is 1
