Given Input Data is 855, 745, 224, 151

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

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 745 is 5 x 149

Prime Factorization of 224 is 2 x 2 x 2 x 2 x 2 x 7

Prime Factorization of 151 is 151

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(855, 745) = 127395

GCD(855, 745) = ( 855 x 745 ) / 127395

GCD(855, 745) = 636975 / 127395

GCD(855, 745) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 224

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

LCM(5, 224) = 1120

GCD(5, 224) = ( 5 x 224 ) / 1120

GCD(5, 224) = 1120 / 1120

GCD(5, 224) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 151

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

LCM(1, 151) = 151

GCD(1, 151) = ( 1 x 151 ) / 151

GCD(1, 151) = 151 / 151

GCD(1, 151) = 1

GCD of 855, 745, 224, 151 is 1
