Therefore, GCD of numbers 263, 465, 391, 555 is 1

Given Input Data is 263, 465, 391, 555

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

Prime Factorization of 263 is 263

Prime Factorization of 465 is 3 x 5 x 31

Prime Factorization of 391 is 17 x 23

Prime Factorization of 555 is 3 x 5 x 37

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(263, 465) = 122295

GCD(263, 465) = ( 263 x 465 ) / 122295

GCD(263, 465) = 122295 / 122295

GCD(263, 465) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 391

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

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

GCD(1, 391) = 391 / 391

GCD(1, 391) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 555

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

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

GCD(1, 555) = 555 / 555

GCD(1, 555) = 1

GCD of 263, 465, 391, 555 is 1
