Therefore, GCD of numbers 18, 9, 63, 88 is 1

Given Input Data is 18, 9, 63, 88

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 9 is 3 x 3

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 88 is 2 x 2 x 2 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(18, 9) = 18

GCD(18, 9) = ( 18 x 9 ) / 18

GCD(18, 9) = 162 / 18

GCD(18, 9) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 63

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

LCM(9, 63) = 63

GCD(9, 63) = ( 9 x 63 ) / 63

GCD(9, 63) = 567 / 63

GCD(9, 63) = 9

Step3:

Here we consider the GCD from the above i.e. 9 as first number and the next as 88

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

LCM(9, 88) = 792

GCD(9, 88) = ( 9 x 88 ) / 792

GCD(9, 88) = 792 / 792

GCD(9, 88) = 1

GCD of 18, 9, 63, 88 is 1
