Therefore, GCD of numbers 287, 861, 46, 220 is 1

Given Input Data is 287, 861, 46, 220

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

Prime Factorization of 287 is 7 x 41

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 46 is 2 x 23

Prime Factorization of 220 is 2 x 2 x 5 x 11

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(287, 861) = 861

GCD(287, 861) = ( 287 x 861 ) / 861

GCD(287, 861) = 247107 / 861

GCD(287, 861) = 287

Step2:

Here we consider the GCD from the above i.e. 287 as first number and the next as 46

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

LCM(287, 46) = 13202

GCD(287, 46) = ( 287 x 46 ) / 13202

GCD(287, 46) = 13202 / 13202

GCD(287, 46) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 220

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

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

GCD(1, 220) = 220 / 220

GCD(1, 220) = 1

GCD of 287, 861, 46, 220 is 1
