Greatest Common Divisior

We found the divisors of 18, 45, 98, 53 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 18, 45, 98, 53 is 1.

Therefore, GCD of numbers 18, 45, 98, 53 is 1

Given Input Data is 18, 45, 98, 53

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

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 98 is 2 x 7 x 7

Prime Factorization of 53 is 53

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(18, 45) = 90

GCD(18, 45) = ( 18 x 45 ) / 90

GCD(18, 45) = 810 / 90

GCD(18, 45) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 98

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

LCM(9, 98) = 882

GCD(9, 98) = ( 9 x 98 ) / 882

GCD(9, 98) = 882 / 882

GCD(9, 98) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 53

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

LCM(1, 53) = 53

GCD(1, 53) = ( 1 x 53 ) / 53

GCD(1, 53) = 53 / 53

GCD(1, 53) = 1

GCD of 18, 45, 98, 53 is 1
