Greatest Common Divisior

We found the divisors of 50, 78, 35, 72 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 50, 78, 35, 72 is 1.

Therefore, GCD of numbers 50, 78, 35, 72 is 1

Given Input Data is 50, 78, 35, 72

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

Prime Factorization of 50 is 2 x 5 x 5

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 35 is 5 x 7

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

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(50, 78) = 1950

GCD(50, 78) = ( 50 x 78 ) / 1950

GCD(50, 78) = 3900 / 1950

GCD(50, 78) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 35

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

LCM(2, 35) = 70

GCD(2, 35) = ( 2 x 35 ) / 70

GCD(2, 35) = 70 / 70

GCD(2, 35) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 72

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

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

GCD(1, 72) = 72 / 72

GCD(1, 72) = 1

GCD of 50, 78, 35, 72 is 1
