Therefore, GCD of numbers 245, 602, 39, 811 is 1

Given Input Data is 245, 602, 39, 811

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

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 602 is 2 x 7 x 43

Prime Factorization of 39 is 3 x 13

Prime Factorization of 811 is 811

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(245, 602) = 21070

GCD(245, 602) = ( 245 x 602 ) / 21070

GCD(245, 602) = 147490 / 21070

GCD(245, 602) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 39

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

LCM(7, 39) = 273

GCD(7, 39) = ( 7 x 39 ) / 273

GCD(7, 39) = 273 / 273

GCD(7, 39) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 811

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

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

GCD(1, 811) = 811 / 811

GCD(1, 811) = 1

GCD of 245, 602, 39, 811 is 1
