Therefore, GCD of numbers 721, 392, 93, 806 is 1

Given Input Data is 721, 392, 93, 806

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

Prime Factorization of 721 is 7 x 103

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 93 is 3 x 31

Prime Factorization of 806 is 2 x 13 x 31

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(721, 392) = 40376

GCD(721, 392) = ( 721 x 392 ) / 40376

GCD(721, 392) = 282632 / 40376

GCD(721, 392) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 93

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

LCM(7, 93) = 651

GCD(7, 93) = ( 7 x 93 ) / 651

GCD(7, 93) = 651 / 651

GCD(7, 93) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 806

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

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

GCD(1, 806) = 806 / 806

GCD(1, 806) = 1

GCD of 721, 392, 93, 806 is 1
