Therefore, GCD of numbers 286, 611, 15, 663 is 1

Given Input Data is 286, 611, 15, 663

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

Prime Factorization of 286 is 2 x 11 x 13

Prime Factorization of 611 is 13 x 47

Prime Factorization of 15 is 3 x 5

Prime Factorization of 663 is 3 x 13 x 17

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(286, 611) = 13442

GCD(286, 611) = ( 286 x 611 ) / 13442

GCD(286, 611) = 174746 / 13442

GCD(286, 611) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 15

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

LCM(13, 15) = 195

GCD(13, 15) = ( 13 x 15 ) / 195

GCD(13, 15) = 195 / 195

GCD(13, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 663

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

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

GCD(1, 663) = 663 / 663

GCD(1, 663) = 1

GCD of 286, 611, 15, 663 is 1
