Greatest Common Divisior

We found the divisors of 98, 30, 51 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 98, 30, 51 is 1.

Therefore, GCD of numbers 98, 30, 51 is 1

Given Input Data is 98, 30, 51

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

Prime Factorization of 98 is 2 x 7 x 7

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 51 is 3 x 17

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(98, 30) = 1470

GCD(98, 30) = ( 98 x 30 ) / 1470

GCD(98, 30) = 2940 / 1470

GCD(98, 30) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 51

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

LCM(2, 51) = 102

GCD(2, 51) = ( 2 x 51 ) / 102

GCD(2, 51) = 102 / 102

GCD(2, 51) = 1

GCD of 98, 30, 51 is 1
