Therefore, GCD of numbers 258, 496, 560, 281 is 1

Given Input Data is 258, 496, 560, 281

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

Prime Factorization of 258 is 2 x 3 x 43

Prime Factorization of 496 is 2 x 2 x 2 x 2 x 31

Prime Factorization of 560 is 2 x 2 x 2 x 2 x 5 x 7

Prime Factorization of 281 is 281

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(258, 496) = 63984

GCD(258, 496) = ( 258 x 496 ) / 63984

GCD(258, 496) = 127968 / 63984

GCD(258, 496) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 560

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

LCM(2, 560) = 560

GCD(2, 560) = ( 2 x 560 ) / 560

GCD(2, 560) = 1120 / 560

GCD(2, 560) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 281

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

LCM(2, 281) = 562

GCD(2, 281) = ( 2 x 281 ) / 562

GCD(2, 281) = 562 / 562

GCD(2, 281) = 1

GCD of 258, 496, 560, 281 is 1
