We found the divisors of 981, 623, 13, 550 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 981, 623, 13, 550 is 1.

Therefore, GCD of numbers 981, 623, 13, 550 is 1

Given Input Data is 981, 623, 13, 550

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

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 623 is 7 x 89

Prime Factorization of 13 is 13

Prime Factorization of 550 is 2 x 5 x 5 x 11

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(981, 623) = 611163

GCD(981, 623) = ( 981 x 623 ) / 611163

GCD(981, 623) = 611163 / 611163

GCD(981, 623) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 13

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

LCM(1, 13) = 13

GCD(1, 13) = ( 1 x 13 ) / 13

GCD(1, 13) = 13 / 13

GCD(1, 13) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 550

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

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

GCD(1, 550) = 550 / 550

GCD(1, 550) = 1

GCD of 981, 623, 13, 550 is 1
