Therefore, GCD of numbers 170, 720, 65, 607 is 1

Given Input Data is 170, 720, 65, 607

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

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime Factorization of 65 is 5 x 13

Prime Factorization of 607 is 607

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(170, 720) = 12240

GCD(170, 720) = ( 170 x 720 ) / 12240

GCD(170, 720) = 122400 / 12240

GCD(170, 720) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 65

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

LCM(10, 65) = 130

GCD(10, 65) = ( 10 x 65 ) / 130

GCD(10, 65) = 650 / 130

GCD(10, 65) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 607

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

LCM(5, 607) = 3035

GCD(5, 607) = ( 5 x 607 ) / 3035

GCD(5, 607) = 3035 / 3035

GCD(5, 607) = 1

GCD of 170, 720, 65, 607 is 1
