Greatest Common Divisior

We found the divisors of 30, 49, 35 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 30, 49, 35 is 1.

Therefore, GCD of numbers 30, 49, 35 is 1

Given Input Data is 30, 49, 35

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 49 is 7 x 7

Prime Factorization of 35 is 5 x 7

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(30, 49) = 1470

GCD(30, 49) = ( 30 x 49 ) / 1470

GCD(30, 49) = 1470 / 1470

GCD(30, 49) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 35

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

LCM(1, 35) = 35

GCD(1, 35) = ( 1 x 35 ) / 35

GCD(1, 35) = 35 / 35

GCD(1, 35) = 1

GCD of 30, 49, 35 is 1
