Therefore, GCD of numbers 18, 918, 715, 784 is 1

Given Input Data is 18, 918, 715, 784

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

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 918 is 2 x 3 x 3 x 3 x 17

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7

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(18, 918) = 918

GCD(18, 918) = ( 18 x 918 ) / 918

GCD(18, 918) = 16524 / 918

GCD(18, 918) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 715

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

LCM(18, 715) = 12870

GCD(18, 715) = ( 18 x 715 ) / 12870

GCD(18, 715) = 12870 / 12870

GCD(18, 715) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 784

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

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

GCD(1, 784) = 784 / 784

GCD(1, 784) = 1

GCD of 18, 918, 715, 784 is 1
