Greatest Common Divisior

We found the divisors of 39, 7, 15, 50 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 39, 7, 15, 50 is 1.

Therefore, GCD of numbers 39, 7, 15, 50 is 1

Given Input Data is 39, 7, 15, 50

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

Prime Factorization of 39 is 3 x 13

Prime Factorization of 7 is 7

Prime Factorization of 15 is 3 x 5

Prime Factorization of 50 is 2 x 5 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(39, 7) = 273

GCD(39, 7) = ( 39 x 7 ) / 273

GCD(39, 7) = 273 / 273

GCD(39, 7) = 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 50

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

LCM(1, 50) = 50

GCD(1, 50) = ( 1 x 50 ) / 50

GCD(1, 50) = 50 / 50

GCD(1, 50) = 1

GCD of 39, 7, 15, 50 is 1
