Given Input Data is 945, 640, 153

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

Prime Factorization of 945 is 3 x 3 x 3 x 5 x 7

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

Prime Factorization of 153 is 3 x 3 x 17

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(945, 640) = 120960

GCD(945, 640) = ( 945 x 640 ) / 120960

GCD(945, 640) = 604800 / 120960

GCD(945, 640) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 153

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

LCM(5, 153) = 765

GCD(5, 153) = ( 5 x 153 ) / 765

GCD(5, 153) = 765 / 765

GCD(5, 153) = 1

GCD of 945, 640, 153 is 1
