Given Input Data is 648, 837, 670

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

Prime Factorization of 648 is 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime Factorization of 837 is 3 x 3 x 3 x 31

Prime Factorization of 670 is 2 x 5 x 67

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(648, 837) = 20088

GCD(648, 837) = ( 648 x 837 ) / 20088

GCD(648, 837) = 542376 / 20088

GCD(648, 837) = 27

Step2:

Here we consider the GCD from the above i.e. 27 as first number and the next as 670

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

LCM(27, 670) = 18090

GCD(27, 670) = ( 27 x 670 ) / 18090

GCD(27, 670) = 18090 / 18090

GCD(27, 670) = 1

GCD of 648, 837, 670 is 1
