Given Input Data is 970, 555, 406

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

Prime Factorization of 970 is 2 x 5 x 97

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 406 is 2 x 7 x 29

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(970, 555) = 107670

GCD(970, 555) = ( 970 x 555 ) / 107670

GCD(970, 555) = 538350 / 107670

GCD(970, 555) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 406

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

LCM(5, 406) = 2030

GCD(5, 406) = ( 5 x 406 ) / 2030

GCD(5, 406) = 2030 / 2030

GCD(5, 406) = 1

GCD of 970, 555, 406 is 1
