Therefore, GCD of numbers 510, 455, 386, 921 is 1

Given Input Data is 510, 455, 386, 921

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

Prime Factorization of 510 is 2 x 3 x 5 x 17

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 386 is 2 x 193

Prime Factorization of 921 is 3 x 307

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(510, 455) = 46410

GCD(510, 455) = ( 510 x 455 ) / 46410

GCD(510, 455) = 232050 / 46410

GCD(510, 455) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 386

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

LCM(5, 386) = 1930

GCD(5, 386) = ( 5 x 386 ) / 1930

GCD(5, 386) = 1930 / 1930

GCD(5, 386) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 921

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

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

GCD(1, 921) = 921 / 921

GCD(1, 921) = 1

GCD of 510, 455, 386, 921 is 1
