Given Input Data is 770, 855, 853, 237

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

Prime Factorization of 770 is 2 x 5 x 7 x 11

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

Prime Factorization of 853 is 853

Prime Factorization of 237 is 3 x 79

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(770, 855) = 131670

GCD(770, 855) = ( 770 x 855 ) / 131670

GCD(770, 855) = 658350 / 131670

GCD(770, 855) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 853

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

LCM(5, 853) = 4265

GCD(5, 853) = ( 5 x 853 ) / 4265

GCD(5, 853) = 4265 / 4265

GCD(5, 853) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 237

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

LCM(1, 237) = 237

GCD(1, 237) = ( 1 x 237 ) / 237

GCD(1, 237) = 237 / 237

GCD(1, 237) = 1

GCD of 770, 855, 853, 237 is 1
