Therefore, GCD of numbers 480, 280, 886, 221 is 1

Given Input Data is 480, 280, 886, 221

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

Prime Factorization of 480 is 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

Prime Factorization of 886 is 2 x 443

Prime Factorization of 221 is 13 x 17

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(480, 280) = 3360

GCD(480, 280) = ( 480 x 280 ) / 3360

GCD(480, 280) = 134400 / 3360

GCD(480, 280) = 40

Step2:

Here we consider the GCD from the above i.e. 40 as first number and the next as 886

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

LCM(40, 886) = 17720

GCD(40, 886) = ( 40 x 886 ) / 17720

GCD(40, 886) = 35440 / 17720

GCD(40, 886) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 221

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

LCM(2, 221) = 442

GCD(2, 221) = ( 2 x 221 ) / 442

GCD(2, 221) = 442 / 442

GCD(2, 221) = 1

GCD of 480, 280, 886, 221 is 1
