We found the divisors of 471, 830, 91, 438 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 471, 830, 91, 438 is 1.

Therefore, GCD of numbers 471, 830, 91, 438 is 1

Given Input Data is 471, 830, 91, 438

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

Prime Factorization of 471 is 3 x 157

Prime Factorization of 830 is 2 x 5 x 83

Prime Factorization of 91 is 7 x 13

Prime Factorization of 438 is 2 x 3 x 73

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(471, 830) = 390930

GCD(471, 830) = ( 471 x 830 ) / 390930

GCD(471, 830) = 390930 / 390930

GCD(471, 830) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 91

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

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

GCD(1, 91) = 91 / 91

GCD(1, 91) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 438

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

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

GCD(1, 438) = 438 / 438

GCD(1, 438) = 1

GCD of 471, 830, 91, 438 is 1
