We found the divisors of 97, 46, 83, 20 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 97, 46, 83, 20 is 1.

Therefore, GCD of numbers 97, 46, 83, 20 is 1

Given Input Data is 97, 46, 83, 20

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

Prime Factorization of 97 is 97

Prime Factorization of 46 is 2 x 23

Prime Factorization of 83 is 83

Prime Factorization of 20 is 2 x 2 x 5

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(97, 46) = 4462

GCD(97, 46) = ( 97 x 46 ) / 4462

GCD(97, 46) = 4462 / 4462

GCD(97, 46) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 83

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

LCM(1, 83) = 83

GCD(1, 83) = ( 1 x 83 ) / 83

GCD(1, 83) = 83 / 83

GCD(1, 83) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

GCD of 97, 46, 83, 20 is 1
