So the Greatest Common Divisior 720, 673, 87 is 1.

Therefore, GCD of numbers 720, 673, 87 is 1

Given Input Data is 720, 673, 87

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

Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime Factorization of 673 is 673

Prime Factorization of 87 is 3 x 29

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(720, 673) = 484560

GCD(720, 673) = ( 720 x 673 ) / 484560

GCD(720, 673) = 484560 / 484560

GCD(720, 673) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 87

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

LCM(1, 87) = 87

GCD(1, 87) = ( 1 x 87 ) / 87

GCD(1, 87) = 87 / 87

GCD(1, 87) = 1

GCD of 720, 673, 87 is 1
