Therefore, GCD of numbers 80, 715, 497, 694 is 1

Given Input Data is 80, 715, 497, 694

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

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 497 is 7 x 71

Prime Factorization of 694 is 2 x 347

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(80, 715) = 11440

GCD(80, 715) = ( 80 x 715 ) / 11440

GCD(80, 715) = 57200 / 11440

GCD(80, 715) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 497

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

LCM(5, 497) = 2485

GCD(5, 497) = ( 5 x 497 ) / 2485

GCD(5, 497) = 2485 / 2485

GCD(5, 497) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 694

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

LCM(1, 694) = 694

GCD(1, 694) = ( 1 x 694 ) / 694

GCD(1, 694) = 694 / 694

GCD(1, 694) = 1

GCD of 80, 715, 497, 694 is 1
