Therefore, GCD of numbers 665, 465, 70, 493 is 1

Given Input Data is 665, 465, 70, 493

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

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 465 is 3 x 5 x 31

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 493 is 17 x 29

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(665, 465) = 61845

GCD(665, 465) = ( 665 x 465 ) / 61845

GCD(665, 465) = 309225 / 61845

GCD(665, 465) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 70

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

LCM(5, 70) = 70

GCD(5, 70) = ( 5 x 70 ) / 70

GCD(5, 70) = 350 / 70

GCD(5, 70) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 493

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

LCM(5, 493) = 2465

GCD(5, 493) = ( 5 x 493 ) / 2465

GCD(5, 493) = 2465 / 2465

GCD(5, 493) = 1

GCD of 665, 465, 70, 493 is 1
