We found the divisors of 731, 470, 61, 430 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 731, 470, 61, 430 is 1.

Therefore, GCD of numbers 731, 470, 61, 430 is 1

Given Input Data is 731, 470, 61, 430

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

Prime Factorization of 731 is 17 x 43

Prime Factorization of 470 is 2 x 5 x 47

Prime Factorization of 61 is 61

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(731, 470) = 343570

GCD(731, 470) = ( 731 x 470 ) / 343570

GCD(731, 470) = 343570 / 343570

GCD(731, 470) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 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 731, 470, 61, 430 is 1
