Therefore, GCD of numbers 561, 851, 319, 246 is 1

Given Input Data is 561, 851, 319, 246

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

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 851 is 23 x 37

Prime Factorization of 319 is 11 x 29

Prime Factorization of 246 is 2 x 3 x 41

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(561, 851) = 477411

GCD(561, 851) = ( 561 x 851 ) / 477411

GCD(561, 851) = 477411 / 477411

GCD(561, 851) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 319

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

LCM(1, 319) = 319

GCD(1, 319) = ( 1 x 319 ) / 319

GCD(1, 319) = 319 / 319

GCD(1, 319) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 246

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

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

GCD(1, 246) = 246 / 246

GCD(1, 246) = 1

GCD of 561, 851, 319, 246 is 1
