Therefore, GCD of numbers 288, 414, 85, 102 is 1

Given Input Data is 288, 414, 85, 102

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

Prime Factorization of 288 is 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime Factorization of 414 is 2 x 3 x 3 x 23

Prime Factorization of 85 is 5 x 17

Prime Factorization of 102 is 2 x 3 x 17

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(288, 414) = 6624

GCD(288, 414) = ( 288 x 414 ) / 6624

GCD(288, 414) = 119232 / 6624

GCD(288, 414) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 85

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

LCM(18, 85) = 1530

GCD(18, 85) = ( 18 x 85 ) / 1530

GCD(18, 85) = 1530 / 1530

GCD(18, 85) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 102

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

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

GCD(1, 102) = 102 / 102

GCD(1, 102) = 1

GCD of 288, 414, 85, 102 is 1
