Therefore, GCD of numbers 630, 408, 81, 550 is 1

Given Input Data is 630, 408, 81, 550

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

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 408 is 2 x 2 x 2 x 3 x 17

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 550 is 2 x 5 x 5 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(630, 408) = 42840

GCD(630, 408) = ( 630 x 408 ) / 42840

GCD(630, 408) = 257040 / 42840

GCD(630, 408) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 81

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

LCM(6, 81) = 162

GCD(6, 81) = ( 6 x 81 ) / 162

GCD(6, 81) = 486 / 162

GCD(6, 81) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 550

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

LCM(3, 550) = 1650

GCD(3, 550) = ( 3 x 550 ) / 1650

GCD(3, 550) = 1650 / 1650

GCD(3, 550) = 1

GCD of 630, 408, 81, 550 is 1
