Therefore, GCD of numbers 424, 128, 15, 699 is 1

Given Input Data is 424, 128, 15, 699

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

Prime Factorization of 424 is 2 x 2 x 2 x 53

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 15 is 3 x 5

Prime Factorization of 699 is 3 x 233

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(424, 128) = 6784

GCD(424, 128) = ( 424 x 128 ) / 6784

GCD(424, 128) = 54272 / 6784

GCD(424, 128) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 15

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

LCM(8, 15) = 120

GCD(8, 15) = ( 8 x 15 ) / 120

GCD(8, 15) = 120 / 120

GCD(8, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 699

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

LCM(1, 699) = 699

GCD(1, 699) = ( 1 x 699 ) / 699

GCD(1, 699) = 699 / 699

GCD(1, 699) = 1

GCD of 424, 128, 15, 699 is 1
