Therefore, GCD of numbers 80, 125, 401, 126 is 1

Given Input Data is 80, 125, 401, 126

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 125 is 5 x 5 x 5

Prime Factorization of 401 is 401

Prime Factorization of 126 is 2 x 3 x 3 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(80, 125) = 2000

GCD(80, 125) = ( 80 x 125 ) / 2000

GCD(80, 125) = 10000 / 2000

GCD(80, 125) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 401

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

LCM(5, 401) = 2005

GCD(5, 401) = ( 5 x 401 ) / 2005

GCD(5, 401) = 2005 / 2005

GCD(5, 401) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 126

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

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

GCD(1, 126) = 126 / 126

GCD(1, 126) = 1

GCD of 80, 125, 401, 126 is 1
