Greatest Common Divisior

We found the divisors of 98, 63, 31 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 98, 63, 31 is 1.

Therefore, GCD of numbers 98, 63, 31 is 1

Given Input Data is 98, 63, 31

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 63 is 3 x 3 x 7

Prime Factorization of 31 is 31

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, 63) = 882

GCD(98, 63) = ( 98 x 63 ) / 882

GCD(98, 63) = 6174 / 882

GCD(98, 63) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 31

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

LCM(7, 31) = 217

GCD(7, 31) = ( 7 x 31 ) / 217

GCD(7, 31) = 217 / 217

GCD(7, 31) = 1

GCD of 98, 63, 31 is 1
