Therefore, GCD of numbers 405, 170, 19, 701 is 1

Given Input Data is 405, 170, 19, 701

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

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 19 is 19

Prime Factorization of 701 is 701

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(405, 170) = 13770

GCD(405, 170) = ( 405 x 170 ) / 13770

GCD(405, 170) = 68850 / 13770

GCD(405, 170) = 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 701

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

LCM(1, 701) = 701

GCD(1, 701) = ( 1 x 701 ) / 701

GCD(1, 701) = 701 / 701

GCD(1, 701) = 1

GCD of 405, 170, 19, 701 is 1
