Therefore, GCD of numbers 13, 455, 526, 777 is 1

Given Input Data is 13, 455, 526, 777

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

Prime Factorization of 13 is 13

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 526 is 2 x 263

Prime Factorization of 777 is 3 x 7 x 37

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(13, 455) = 455

GCD(13, 455) = ( 13 x 455 ) / 455

GCD(13, 455) = 5915 / 455

GCD(13, 455) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 526

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

LCM(13, 526) = 6838

GCD(13, 526) = ( 13 x 526 ) / 6838

GCD(13, 526) = 6838 / 6838

GCD(13, 526) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 777

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

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

GCD(1, 777) = 777 / 777

GCD(1, 777) = 1

GCD of 13, 455, 526, 777 is 1
