We found the divisors of 61, 255, 503, 486 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 61, 255, 503, 486 is 1.

Therefore, GCD of numbers 61, 255, 503, 486 is 1

Given Input Data is 61, 255, 503, 486

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

Prime Factorization of 61 is 61

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 503 is 503

Prime Factorization of 486 is 2 x 3 x 3 x 3 x 3 x 3

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(61, 255) = 15555

GCD(61, 255) = ( 61 x 255 ) / 15555

GCD(61, 255) = 15555 / 15555

GCD(61, 255) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 503

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

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

GCD(1, 503) = 503 / 503

GCD(1, 503) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 486

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

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

GCD(1, 486) = 486 / 486

GCD(1, 486) = 1

GCD of 61, 255, 503, 486 is 1
