So the Greatest Common Divisior 484, 153, 481, 771 is 1.

Therefore, GCD of numbers 484, 153, 481, 771 is 1

Given Input Data is 484, 153, 481, 771

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

Prime Factorization of 484 is 2 x 2 x 11 x 11

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 481 is 13 x 37

Prime Factorization of 771 is 3 x 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(484, 153) = 74052

GCD(484, 153) = ( 484 x 153 ) / 74052

GCD(484, 153) = 74052 / 74052

GCD(484, 153) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 481

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

LCM(1, 481) = 481

GCD(1, 481) = ( 1 x 481 ) / 481

GCD(1, 481) = 481 / 481

GCD(1, 481) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 771

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

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

GCD(1, 771) = 771 / 771

GCD(1, 771) = 1

GCD of 484, 153, 481, 771 is 1
