Therefore, GCD of numbers 90, 306, 533, 787 is 1

Given Input Data is 90, 306, 533, 787

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 306 is 2 x 3 x 3 x 17

Prime Factorization of 533 is 13 x 41

Prime Factorization of 787 is 787

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, 306) = 1530

GCD(90, 306) = ( 90 x 306 ) / 1530

GCD(90, 306) = 27540 / 1530

GCD(90, 306) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 533

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

LCM(18, 533) = 9594

GCD(18, 533) = ( 18 x 533 ) / 9594

GCD(18, 533) = 9594 / 9594

GCD(18, 533) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 787

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

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

GCD(1, 787) = 787 / 787

GCD(1, 787) = 1

GCD of 90, 306, 533, 787 is 1
