Given Input Data is 90, 850, 645, 581

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

Prime Factorization of 90 is 2 x 3 x 3 x 5

Prime Factorization of 850 is 2 x 5 x 5 x 17

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 581 is 7 x 83

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(90, 850) = 7650

GCD(90, 850) = ( 90 x 850 ) / 7650

GCD(90, 850) = 76500 / 7650

GCD(90, 850) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 645

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

LCM(10, 645) = 1290

GCD(10, 645) = ( 10 x 645 ) / 1290

GCD(10, 645) = 6450 / 1290

GCD(10, 645) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 581

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

LCM(5, 581) = 2905

GCD(5, 581) = ( 5 x 581 ) / 2905

GCD(5, 581) = 2905 / 2905

GCD(5, 581) = 1

GCD of 90, 850, 645, 581 is 1
