Therefore, GCD of numbers 15, 190, 866, 902 is 1

Given Input Data is 15, 190, 866, 902

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 190 is 2 x 5 x 19

Prime Factorization of 866 is 2 x 433

Prime Factorization of 902 is 2 x 11 x 41

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(15, 190) = 570

GCD(15, 190) = ( 15 x 190 ) / 570

GCD(15, 190) = 2850 / 570

GCD(15, 190) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 866

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

LCM(5, 866) = 4330

GCD(5, 866) = ( 5 x 866 ) / 4330

GCD(5, 866) = 4330 / 4330

GCD(5, 866) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 902

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

LCM(1, 902) = 902

GCD(1, 902) = ( 1 x 902 ) / 902

GCD(1, 902) = 902 / 902

GCD(1, 902) = 1

GCD of 15, 190, 866, 902 is 1
