We found the divisors of 98, 30, 95, 75 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 98, 30, 95, 75 is 1.

Therefore, GCD of numbers 98, 30, 95, 75 is 1

Given Input Data is 98, 30, 95, 75

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 95 is 5 x 19

Prime Factorization of 75 is 3 x 5 x 5

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 95

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

LCM(2, 95) = 190

GCD(2, 95) = ( 2 x 95 ) / 190

GCD(2, 95) = 190 / 190

GCD(2, 95) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 75

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

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

GCD(1, 75) = 75 / 75

GCD(1, 75) = 1

GCD of 98, 30, 95, 75 is 1
