Therefore, GCD of numbers 730, 480, 63, 257 is 1

Given Input Data is 730, 480, 63, 257

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

Prime Factorization of 730 is 2 x 5 x 73

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

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 257 is 257

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(730, 480) = 35040

GCD(730, 480) = ( 730 x 480 ) / 35040

GCD(730, 480) = 350400 / 35040

GCD(730, 480) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 63

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

LCM(10, 63) = 630

GCD(10, 63) = ( 10 x 63 ) / 630

GCD(10, 63) = 630 / 630

GCD(10, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 257

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

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

GCD(1, 257) = 257 / 257

GCD(1, 257) = 1

GCD of 730, 480, 63, 257 is 1
