We found the divisors of 485, 154, 56, 549 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 485, 154, 56, 549 is 1.

Therefore, GCD of numbers 485, 154, 56, 549 is 1

Given Input Data is 485, 154, 56, 549

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

Prime Factorization of 485 is 5 x 97

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 56 is 2 x 2 x 2 x 7

Prime Factorization of 549 is 3 x 3 x 61

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(485, 154) = 74690

GCD(485, 154) = ( 485 x 154 ) / 74690

GCD(485, 154) = 74690 / 74690

GCD(485, 154) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 56

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

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

GCD(1, 56) = 56 / 56

GCD(1, 56) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 549

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

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

GCD(1, 549) = 549 / 549

GCD(1, 549) = 1

GCD of 485, 154, 56, 549 is 1
