So the Greatest Common Divisior 633, 643, 620 is 1.

Therefore, GCD of numbers 633, 643, 620 is 1

Given Input Data is 633, 643, 620

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

Prime Factorization of 633 is 3 x 211

Prime Factorization of 643 is 643

Prime Factorization of 620 is 2 x 2 x 5 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(633, 643) = 407019

GCD(633, 643) = ( 633 x 643 ) / 407019

GCD(633, 643) = 407019 / 407019

GCD(633, 643) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 620

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

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

GCD(1, 620) = 620 / 620

GCD(1, 620) = 1

GCD of 633, 643, 620 is 1
