We found the divisors of 29, 89, 65, 90 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 29, 89, 65, 90 is 1.

Therefore, GCD of numbers 29, 89, 65, 90 is 1

Given Input Data is 29, 89, 65, 90

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

Prime Factorization of 29 is 29

Prime Factorization of 89 is 89

Prime Factorization of 65 is 5 x 13

Prime Factorization of 90 is 2 x 3 x 3 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(29, 89) = 2581

GCD(29, 89) = ( 29 x 89 ) / 2581

GCD(29, 89) = 2581 / 2581

GCD(29, 89) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 65

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

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

GCD(1, 65) = 65 / 65

GCD(1, 65) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 90

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

LCM(1, 90) = 90

GCD(1, 90) = ( 1 x 90 ) / 90

GCD(1, 90) = 90 / 90

GCD(1, 90) = 1

GCD of 29, 89, 65, 90 is 1
