Therefore, GCD of numbers 80, 158, 481, 628 is 1

Given Input Data is 80, 158, 481, 628

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 158 is 2 x 79

Prime Factorization of 481 is 13 x 37

Prime Factorization of 628 is 2 x 2 x 157

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, 158) = 6320

GCD(80, 158) = ( 80 x 158 ) / 6320

GCD(80, 158) = 12640 / 6320

GCD(80, 158) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 481

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

LCM(2, 481) = 962

GCD(2, 481) = ( 2 x 481 ) / 962

GCD(2, 481) = 962 / 962

GCD(2, 481) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 628

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

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

GCD(1, 628) = 628 / 628

GCD(1, 628) = 1

GCD of 80, 158, 481, 628 is 1
