Therefore, GCD of numbers 790, 655, 447, 441 is 1

Given Input Data is 790, 655, 447, 441

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

Prime Factorization of 790 is 2 x 5 x 79

Prime Factorization of 655 is 5 x 131

Prime Factorization of 447 is 3 x 149

Prime Factorization of 441 is 3 x 3 x 7 x 7

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(790, 655) = 103490

GCD(790, 655) = ( 790 x 655 ) / 103490

GCD(790, 655) = 517450 / 103490

GCD(790, 655) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 447

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

LCM(5, 447) = 2235

GCD(5, 447) = ( 5 x 447 ) / 2235

GCD(5, 447) = 2235 / 2235

GCD(5, 447) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 441

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

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

GCD(1, 441) = 441 / 441

GCD(1, 441) = 1

GCD of 790, 655, 447, 441 is 1
