Given Input Data is 830, 775, 102, 212

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

Prime Factorization of 830 is 2 x 5 x 83

Prime Factorization of 775 is 5 x 5 x 31

Prime Factorization of 102 is 2 x 3 x 17

Prime Factorization of 212 is 2 x 2 x 53

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(830, 775) = 128650

GCD(830, 775) = ( 830 x 775 ) / 128650

GCD(830, 775) = 643250 / 128650

GCD(830, 775) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 102

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

LCM(5, 102) = 510

GCD(5, 102) = ( 5 x 102 ) / 510

GCD(5, 102) = 510 / 510

GCD(5, 102) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 212

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

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

GCD(1, 212) = 212 / 212

GCD(1, 212) = 1

GCD of 830, 775, 102, 212 is 1
