Therefore, GCD of numbers 860, 245, 912, 228 is 1

Given Input Data is 860, 245, 912, 228

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

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 912 is 2 x 2 x 2 x 2 x 3 x 19

Prime Factorization of 228 is 2 x 2 x 3 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(860, 245) = 42140

GCD(860, 245) = ( 860 x 245 ) / 42140

GCD(860, 245) = 210700 / 42140

GCD(860, 245) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 912

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

LCM(5, 912) = 4560

GCD(5, 912) = ( 5 x 912 ) / 4560

GCD(5, 912) = 4560 / 4560

GCD(5, 912) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 228

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

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

GCD(1, 228) = 228 / 228

GCD(1, 228) = 1

GCD of 860, 245, 912, 228 is 1
