Therefore, GCD of numbers 20, 340, 439, 807 is 1

Given Input Data is 20, 340, 439, 807

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

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 340 is 2 x 2 x 5 x 17

Prime Factorization of 439 is 439

Prime Factorization of 807 is 3 x 269

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(20, 340) = 340

GCD(20, 340) = ( 20 x 340 ) / 340

GCD(20, 340) = 6800 / 340

GCD(20, 340) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 439

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

LCM(20, 439) = 8780

GCD(20, 439) = ( 20 x 439 ) / 8780

GCD(20, 439) = 8780 / 8780

GCD(20, 439) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 807

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

LCM(1, 807) = 807

GCD(1, 807) = ( 1 x 807 ) / 807

GCD(1, 807) = 807 / 807

GCD(1, 807) = 1

GCD of 20, 340, 439, 807 is 1
