We found the divisors of 124, 484, 31, 430 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 124, 484, 31, 430 is 1.

Therefore, GCD of numbers 124, 484, 31, 430 is 1

Given Input Data is 124, 484, 31, 430

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

Prime Factorization of 124 is 2 x 2 x 31

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

Prime Factorization of 31 is 31

Prime Factorization of 430 is 2 x 5 x 43

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(124, 484) = 15004

GCD(124, 484) = ( 124 x 484 ) / 15004

GCD(124, 484) = 60016 / 15004

GCD(124, 484) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 31

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

LCM(4, 31) = 124

GCD(4, 31) = ( 4 x 31 ) / 124

GCD(4, 31) = 124 / 124

GCD(4, 31) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 430

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

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

GCD(1, 430) = 430 / 430

GCD(1, 430) = 1

GCD of 124, 484, 31, 430 is 1
