Greatest Common Divisior

We found the divisors of 153, 730, 61, 261 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 153, 730, 61, 261 is 1.

Therefore, GCD of numbers 153, 730, 61, 261 is 1

Given Input Data is 153, 730, 61, 261

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

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 730 is 2 x 5 x 73

Prime Factorization of 61 is 61

Prime Factorization of 261 is 3 x 3 x 29

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(153, 730) = 111690

GCD(153, 730) = ( 153 x 730 ) / 111690

GCD(153, 730) = 111690 / 111690

GCD(153, 730) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 261

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

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

GCD(1, 261) = 261 / 261

GCD(1, 261) = 1

GCD of 153, 730, 61, 261 is 1
