We found the divisors of 76, 59, 15, 65 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 76, 59, 15, 65 is 1.

Therefore, GCD of numbers 76, 59, 15, 65 is 1

Given Input Data is 76, 59, 15, 65

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

Prime Factorization of 76 is 2 x 2 x 19

Prime Factorization of 59 is 59

Prime Factorization of 15 is 3 x 5

Prime Factorization of 65 is 5 x 13

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(76, 59) = 4484

GCD(76, 59) = ( 76 x 59 ) / 4484

GCD(76, 59) = 4484 / 4484

GCD(76, 59) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

Step3:

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

GCD of 76, 59, 15, 65 is 1
