Therefore, GCD of numbers 581, 357, 81 is 1

Given Input Data is 581, 357, 81

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

Prime Factorization of 581 is 7 x 83

Prime Factorization of 357 is 3 x 7 x 17

Prime Factorization of 81 is 3 x 3 x 3 x 3

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(581, 357) = 29631

GCD(581, 357) = ( 581 x 357 ) / 29631

GCD(581, 357) = 207417 / 29631

GCD(581, 357) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 81

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

LCM(7, 81) = 567

GCD(7, 81) = ( 7 x 81 ) / 567

GCD(7, 81) = 567 / 567

GCD(7, 81) = 1

GCD of 581, 357, 81 is 1
