Greatest Common Divisior

We found the divisors of 71, 620, 103, 442 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 71, 620, 103, 442 is 1.

Therefore, GCD of numbers 71, 620, 103, 442 is 1

Given Input Data is 71, 620, 103, 442

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

Prime Factorization of 71 is 71

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 103 is 103

Prime Factorization of 442 is 2 x 13 x 17

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(71, 620) = 44020

GCD(71, 620) = ( 71 x 620 ) / 44020

GCD(71, 620) = 44020 / 44020

GCD(71, 620) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 103

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

LCM(1, 103) = 103

GCD(1, 103) = ( 1 x 103 ) / 103

GCD(1, 103) = 103 / 103

GCD(1, 103) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 442

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

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

GCD(1, 442) = 442 / 442

GCD(1, 442) = 1

GCD of 71, 620, 103, 442 is 1
