Therefore, GCD of numbers 245, 272, 862 is 1

Given Input Data is 245, 272, 862

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

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 272 is 2 x 2 x 2 x 2 x 17

Prime Factorization of 862 is 2 x 431

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(245, 272) = 66640

GCD(245, 272) = ( 245 x 272 ) / 66640

GCD(245, 272) = 66640 / 66640

GCD(245, 272) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 862

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

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

GCD(1, 862) = 862 / 862

GCD(1, 862) = 1

GCD of 245, 272, 862 is 1
