Therefore, GCD of numbers 386, 193, 15, 870 is 1

Given Input Data is 386, 193, 15, 870

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

Prime Factorization of 386 is 2 x 193

Prime Factorization of 193 is 193

Prime Factorization of 15 is 3 x 5

Prime Factorization of 870 is 2 x 3 x 5 x 29

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(386, 193) = 386

GCD(386, 193) = ( 386 x 193 ) / 386

GCD(386, 193) = 74498 / 386

GCD(386, 193) = 193

Step2:

Here we consider the GCD from the above i.e. 193 as first number and the next as 15

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

LCM(193, 15) = 2895

GCD(193, 15) = ( 193 x 15 ) / 2895

GCD(193, 15) = 2895 / 2895

GCD(193, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 870

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

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

GCD(1, 870) = 870 / 870

GCD(1, 870) = 1

GCD of 386, 193, 15, 870 is 1
