Therefore, GCD of numbers 445, 534, 21, 382 is 1

Given Input Data is 445, 534, 21, 382

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

Prime Factorization of 445 is 5 x 89

Prime Factorization of 534 is 2 x 3 x 89

Prime Factorization of 21 is 3 x 7

Prime Factorization of 382 is 2 x 191

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(445, 534) = 2670

GCD(445, 534) = ( 445 x 534 ) / 2670

GCD(445, 534) = 237630 / 2670

GCD(445, 534) = 89

Step2:

Here we consider the GCD from the above i.e. 89 as first number and the next as 21

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

LCM(89, 21) = 1869

GCD(89, 21) = ( 89 x 21 ) / 1869

GCD(89, 21) = 1869 / 1869

GCD(89, 21) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 382

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

LCM(1, 382) = 382

GCD(1, 382) = ( 1 x 382 ) / 382

GCD(1, 382) = 382 / 382

GCD(1, 382) = 1

GCD of 445, 534, 21, 382 is 1
