Therefore, GCD of numbers 15, 955, 186, 286 is 1

Given Input Data is 15, 955, 186, 286

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 955 is 5 x 191

Prime Factorization of 186 is 2 x 3 x 31

Prime Factorization of 286 is 2 x 11 x 13

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, 955) = 2865

GCD(15, 955) = ( 15 x 955 ) / 2865

GCD(15, 955) = 14325 / 2865

GCD(15, 955) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 186

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

LCM(5, 186) = 930

GCD(5, 186) = ( 5 x 186 ) / 930

GCD(5, 186) = 930 / 930

GCD(5, 186) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 286

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

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

GCD(1, 286) = 286 / 286

GCD(1, 286) = 1

GCD of 15, 955, 186, 286 is 1
