Given Input Data is 945, 890, 439, 575

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 890 is 2 x 5 x 89

Prime Factorization of 439 is 439

Prime Factorization of 575 is 5 x 5 x 23

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, 890) = 168210

GCD(945, 890) = ( 945 x 890 ) / 168210

GCD(945, 890) = 841050 / 168210

GCD(945, 890) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 439

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

LCM(5, 439) = 2195

GCD(5, 439) = ( 5 x 439 ) / 2195

GCD(5, 439) = 2195 / 2195

GCD(5, 439) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 575

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

LCM(1, 575) = 575

GCD(1, 575) = ( 1 x 575 ) / 575

GCD(1, 575) = 575 / 575

GCD(1, 575) = 1

GCD of 945, 890, 439, 575 is 1
