So the Greatest Common Divisior 190, 210, 862, 443 is 1.

Therefore, GCD of numbers 190, 210, 862, 443 is 1

Given Input Data is 190, 210, 862, 443

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

Prime Factorization of 190 is 2 x 5 x 19

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 862 is 2 x 431

Prime Factorization of 443 is 443

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(190, 210) = 3990

GCD(190, 210) = ( 190 x 210 ) / 3990

GCD(190, 210) = 39900 / 3990

GCD(190, 210) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 862

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

LCM(10, 862) = 4310

GCD(10, 862) = ( 10 x 862 ) / 4310

GCD(10, 862) = 8620 / 4310

GCD(10, 862) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 443

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

LCM(2, 443) = 886

GCD(2, 443) = ( 2 x 443 ) / 886

GCD(2, 443) = 886 / 886

GCD(2, 443) = 1

GCD of 190, 210, 862, 443 is 1
