Therefore, GCD of numbers 645, 576, 30, 910 is 1

Given Input Data is 645, 576, 30, 910

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

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 576 is 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 910 is 2 x 5 x 7 x 13

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(645, 576) = 123840

GCD(645, 576) = ( 645 x 576 ) / 123840

GCD(645, 576) = 371520 / 123840

GCD(645, 576) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 30

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

LCM(3, 30) = 30

GCD(3, 30) = ( 3 x 30 ) / 30

GCD(3, 30) = 90 / 30

GCD(3, 30) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 910

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

LCM(3, 910) = 2730

GCD(3, 910) = ( 3 x 910 ) / 2730

GCD(3, 910) = 2730 / 2730

GCD(3, 910) = 1

GCD of 645, 576, 30, 910 is 1
