Greatest Common Divisior

We found the divisors of 305, 561, 147, 614 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 305, 561, 147, 614 is 1.

Therefore, GCD of numbers 305, 561, 147, 614 is 1

Given Input Data is 305, 561, 147, 614

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

Prime Factorization of 305 is 5 x 61

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 147 is 3 x 7 x 7

Prime Factorization of 614 is 2 x 307

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(305, 561) = 171105

GCD(305, 561) = ( 305 x 561 ) / 171105

GCD(305, 561) = 171105 / 171105

GCD(305, 561) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 147

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

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

GCD(1, 147) = 147 / 147

GCD(1, 147) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 614

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

LCM(1, 614) = 614

GCD(1, 614) = ( 1 x 614 ) / 614

GCD(1, 614) = 614 / 614

GCD(1, 614) = 1

GCD of 305, 561, 147, 614 is 1
