Therefore, GCD of numbers 715, 979, 69, 497 is 1

Given Input Data is 715, 979, 69, 497

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

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 979 is 11 x 89

Prime Factorization of 69 is 3 x 23

Prime Factorization of 497 is 7 x 71

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(715, 979) = 63635

GCD(715, 979) = ( 715 x 979 ) / 63635

GCD(715, 979) = 699985 / 63635

GCD(715, 979) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 69

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

LCM(11, 69) = 759

GCD(11, 69) = ( 11 x 69 ) / 759

GCD(11, 69) = 759 / 759

GCD(11, 69) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 497

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

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

GCD(1, 497) = 497 / 497

GCD(1, 497) = 1

GCD of 715, 979, 69, 497 is 1
