Given Input Data is 90, 543, 490, 891

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 543 is 3 x 181

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

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, 543) = 16290

GCD(90, 543) = ( 90 x 543 ) / 16290

GCD(90, 543) = 48870 / 16290

GCD(90, 543) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 490

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

LCM(3, 490) = 1470

GCD(3, 490) = ( 3 x 490 ) / 1470

GCD(3, 490) = 1470 / 1470

GCD(3, 490) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 891

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

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

GCD(1, 891) = 891 / 891

GCD(1, 891) = 1

GCD of 90, 543, 490, 891 is 1
