Therefore, GCD of numbers 66, 803, 174, 855 is 1

Given Input Data is 66, 803, 174, 855

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

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 803 is 11 x 73

Prime Factorization of 174 is 2 x 3 x 29

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

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(66, 803) = 4818

GCD(66, 803) = ( 66 x 803 ) / 4818

GCD(66, 803) = 52998 / 4818

GCD(66, 803) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 174

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

LCM(11, 174) = 1914

GCD(11, 174) = ( 11 x 174 ) / 1914

GCD(11, 174) = 1914 / 1914

GCD(11, 174) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 855

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

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

GCD(1, 855) = 855 / 855

GCD(1, 855) = 1

GCD of 66, 803, 174, 855 is 1
