Therefore, GCD of numbers 130, 955, 93, 645 is 1

Given Input Data is 130, 955, 93, 645

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 955 is 5 x 191

Prime Factorization of 93 is 3 x 31

Prime Factorization of 645 is 3 x 5 x 43

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, 955) = 24830

GCD(130, 955) = ( 130 x 955 ) / 24830

GCD(130, 955) = 124150 / 24830

GCD(130, 955) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 93

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

LCM(5, 93) = 465

GCD(5, 93) = ( 5 x 93 ) / 465

GCD(5, 93) = 465 / 465

GCD(5, 93) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 645

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

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

GCD(1, 645) = 645 / 645

GCD(1, 645) = 1

GCD of 130, 955, 93, 645 is 1
