Therefore, GCD of numbers 160, 690, 721 is 1

Given Input Data is 160, 690, 721

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

Prime Factorization of 160 is 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 690 is 2 x 3 x 5 x 23

Prime Factorization of 721 is 7 x 103

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(160, 690) = 11040

GCD(160, 690) = ( 160 x 690 ) / 11040

GCD(160, 690) = 110400 / 11040

GCD(160, 690) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 721

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

LCM(10, 721) = 7210

GCD(10, 721) = ( 10 x 721 ) / 7210

GCD(10, 721) = 7210 / 7210

GCD(10, 721) = 1

GCD of 160, 690, 721 is 1
