Therefore, GCD of numbers 665, 710, 581, 145 is 1

Given Input Data is 665, 710, 581, 145

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 710 is 2 x 5 x 71

Prime Factorization of 581 is 7 x 83

Prime Factorization of 145 is 5 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, 710) = 94430

GCD(665, 710) = ( 665 x 710 ) / 94430

GCD(665, 710) = 472150 / 94430

GCD(665, 710) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 581

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

LCM(5, 581) = 2905

GCD(5, 581) = ( 5 x 581 ) / 2905

GCD(5, 581) = 2905 / 2905

GCD(5, 581) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 145

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

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

GCD(1, 145) = 145 / 145

GCD(1, 145) = 1

GCD of 665, 710, 581, 145 is 1
