Greatest Common Divisior

We found the divisors of 59, 43, 30, 15 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 59, 43, 30, 15 is 1.

Therefore, GCD of numbers 59, 43, 30, 15 is 1

Given Input Data is 59, 43, 30, 15

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

Prime Factorization of 59 is 59

Prime Factorization of 43 is 43

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 15 is 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(59, 43) = 2537

GCD(59, 43) = ( 59 x 43 ) / 2537

GCD(59, 43) = 2537 / 2537

GCD(59, 43) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 30

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

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

GCD(1, 30) = 30 / 30

GCD(1, 30) = 1

Step3:

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

GCD of 59, 43, 30, 15 is 1
