Given Input Data is 561, 915, 802

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

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 915 is 3 x 5 x 61

Prime Factorization of 802 is 2 x 401

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(561, 915) = 171105

GCD(561, 915) = ( 561 x 915 ) / 171105

GCD(561, 915) = 513315 / 171105

GCD(561, 915) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 802

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

LCM(3, 802) = 2406

GCD(3, 802) = ( 3 x 802 ) / 2406

GCD(3, 802) = 2406 / 2406

GCD(3, 802) = 1

GCD of 561, 915, 802 is 1
