Therefore, GCD of numbers 555, 800, 61, 640 is 1

Given Input Data is 555, 800, 61, 640

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

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 800 is 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime Factorization of 61 is 61

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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(555, 800) = 88800

GCD(555, 800) = ( 555 x 800 ) / 88800

GCD(555, 800) = 444000 / 88800

GCD(555, 800) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 61

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

LCM(5, 61) = 305

GCD(5, 61) = ( 5 x 61 ) / 305

GCD(5, 61) = 305 / 305

GCD(5, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 640

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

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

GCD(1, 640) = 640 / 640

GCD(1, 640) = 1

GCD of 555, 800, 61, 640 is 1
