Given Input Data is 707, 413, 666, 621

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

Prime Factorization of 707 is 7 x 101

Prime Factorization of 413 is 7 x 59

Prime Factorization of 666 is 2 x 3 x 3 x 37

Prime Factorization of 621 is 3 x 3 x 3 x 23

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(707, 413) = 41713

GCD(707, 413) = ( 707 x 413 ) / 41713

GCD(707, 413) = 291991 / 41713

GCD(707, 413) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 666

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

LCM(7, 666) = 4662

GCD(7, 666) = ( 7 x 666 ) / 4662

GCD(7, 666) = 4662 / 4662

GCD(7, 666) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 621

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

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

GCD(1, 621) = 621 / 621

GCD(1, 621) = 1

GCD of 707, 413, 666, 621 is 1
