Therefore, GCD of numbers 444, 558, 40, 387 is 1

Given Input Data is 444, 558, 40, 387

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

Prime Factorization of 444 is 2 x 2 x 3 x 37

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 387 is 3 x 3 x 43

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(444, 558) = 41292

GCD(444, 558) = ( 444 x 558 ) / 41292

GCD(444, 558) = 247752 / 41292

GCD(444, 558) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 40

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

LCM(6, 40) = 120

GCD(6, 40) = ( 6 x 40 ) / 120

GCD(6, 40) = 240 / 120

GCD(6, 40) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 387

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

LCM(2, 387) = 774

GCD(2, 387) = ( 2 x 387 ) / 774

GCD(2, 387) = 774 / 774

GCD(2, 387) = 1

GCD of 444, 558, 40, 387 is 1
