Given Input Data is 903, 860, 215

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

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 215 is 5 x 43

Highest common occurrences in the given inputs are 43¹

Multiplying them we get the GCD as 43

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(903, 860) = 18060

GCD(903, 860) = ( 903 x 860 ) / 18060

GCD(903, 860) = 776580 / 18060

GCD(903, 860) = 43

Step2:

Here we consider the GCD from the above i.e. 43 as first number and the next as 215

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

LCM(43, 215) = 215

GCD(43, 215) = ( 43 x 215 ) / 215

GCD(43, 215) = 9245 / 215

GCD(43, 215) = 43

GCD of 903, 860, 215 is 43
