We found the divisors of 63, 30, 98 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 63, 30, 98 is 1.

Therefore, GCD of numbers 63, 30, 98 is 1

Given Input Data is 63, 30, 98

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

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 98 is 2 x 7 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(63, 30) = 630

GCD(63, 30) = ( 63 x 30 ) / 630

GCD(63, 30) = 1890 / 630

GCD(63, 30) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 98

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

LCM(3, 98) = 294

GCD(3, 98) = ( 3 x 98 ) / 294

GCD(3, 98) = 294 / 294

GCD(3, 98) = 1

GCD of 63, 30, 98 is 1
