So the Greatest Common Divisior 843, 257, 43 is 1.

Therefore, GCD of numbers 843, 257, 43 is 1

Given Input Data is 843, 257, 43

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

Prime Factorization of 843 is 3 x 281

Prime Factorization of 257 is 257

Prime Factorization of 43 is 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(843, 257) = 216651

GCD(843, 257) = ( 843 x 257 ) / 216651

GCD(843, 257) = 216651 / 216651

GCD(843, 257) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 43

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

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

GCD(1, 43) = 43 / 43

GCD(1, 43) = 1

GCD of 843, 257, 43 is 1
