Therefore, GCD of numbers 130, 940, 129, 445 is 1

Given Input Data is 130, 940, 129, 445

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

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 940 is 2 x 2 x 5 x 47

Prime Factorization of 129 is 3 x 43

Prime Factorization of 445 is 5 x 89

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(130, 940) = 12220

GCD(130, 940) = ( 130 x 940 ) / 12220

GCD(130, 940) = 122200 / 12220

GCD(130, 940) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 129

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

LCM(10, 129) = 1290

GCD(10, 129) = ( 10 x 129 ) / 1290

GCD(10, 129) = 1290 / 1290

GCD(10, 129) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 445

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

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

GCD(1, 445) = 445 / 445

GCD(1, 445) = 1

GCD of 130, 940, 129, 445 is 1
