Given Input Data is 805, 450, 553, 261

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

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5

Prime Factorization of 553 is 7 x 79

Prime Factorization of 261 is 3 x 3 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(805, 450) = 72450

GCD(805, 450) = ( 805 x 450 ) / 72450

GCD(805, 450) = 362250 / 72450

GCD(805, 450) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 553

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

LCM(5, 553) = 2765

GCD(5, 553) = ( 5 x 553 ) / 2765

GCD(5, 553) = 2765 / 2765

GCD(5, 553) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 261

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

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

GCD(1, 261) = 261 / 261

GCD(1, 261) = 1

GCD of 805, 450, 553, 261 is 1
