We found the divisors of 283, 421, 220, 465 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 283, 421, 220, 465 is 1.

Therefore, GCD of numbers 283, 421, 220, 465 is 1

Given Input Data is 283, 421, 220, 465

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

Prime Factorization of 283 is 283

Prime Factorization of 421 is 421

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

Prime Factorization of 465 is 3 x 5 x 31

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(283, 421) = 119143

GCD(283, 421) = ( 283 x 421 ) / 119143

GCD(283, 421) = 119143 / 119143

GCD(283, 421) = 1

Step2:

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

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 465

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

LCM(1, 465) = 465

GCD(1, 465) = ( 1 x 465 ) / 465

GCD(1, 465) = 465 / 465

GCD(1, 465) = 1

GCD of 283, 421, 220, 465 is 1
