Therefore, GCD of numbers 571, 978, 143, 957 is 1

Given Input Data is 571, 978, 143, 957

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

Prime Factorization of 571 is 571

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 143 is 11 x 13

Prime Factorization of 957 is 3 x 11 x 29

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(571, 978) = 558438

GCD(571, 978) = ( 571 x 978 ) / 558438

GCD(571, 978) = 558438 / 558438

GCD(571, 978) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 143

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

LCM(1, 143) = 143

GCD(1, 143) = ( 1 x 143 ) / 143

GCD(1, 143) = 143 / 143

GCD(1, 143) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 957

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

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

GCD(1, 957) = 957 / 957

GCD(1, 957) = 1

GCD of 571, 978, 143, 957 is 1
