Given Input Data is 511, 651, 980, 481

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

Prime Factorization of 511 is 7 x 73

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

Prime Factorization of 481 is 13 x 37

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(511, 651) = 47523

GCD(511, 651) = ( 511 x 651 ) / 47523

GCD(511, 651) = 332661 / 47523

GCD(511, 651) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 980

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

LCM(7, 980) = 980

GCD(7, 980) = ( 7 x 980 ) / 980

GCD(7, 980) = 6860 / 980

GCD(7, 980) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 481

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

LCM(7, 481) = 3367

GCD(7, 481) = ( 7 x 481 ) / 3367

GCD(7, 481) = 3367 / 3367

GCD(7, 481) = 1

GCD of 511, 651, 980, 481 is 1
