We found the divisors of 74, 59, 20, 20 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 74, 59, 20, 20 is 1.

Therefore, GCD of numbers 74, 59, 20, 20 is 1

Given Input Data is 74, 59, 20, 20

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

Prime Factorization of 74 is 2 x 37

Prime Factorization of 59 is 59

Prime Factorization of 20 is 2 x 2 x 5

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(74, 59) = 4366

GCD(74, 59) = ( 74 x 59 ) / 4366

GCD(74, 59) = 4366 / 4366

GCD(74, 59) = 1

Step2:

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

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 74, 59, 20, 20 is 1
