Therefore, GCD of numbers 390, 325, 68, 880 is 1

Given Input Data is 390, 325, 68, 880

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

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 325 is 5 x 5 x 13

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 880 is 2 x 2 x 2 x 2 x 5 x 11

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(390, 325) = 1950

GCD(390, 325) = ( 390 x 325 ) / 1950

GCD(390, 325) = 126750 / 1950

GCD(390, 325) = 65

Step2:

Here we consider the GCD from the above i.e. 65 as first number and the next as 68

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

LCM(65, 68) = 4420

GCD(65, 68) = ( 65 x 68 ) / 4420

GCD(65, 68) = 4420 / 4420

GCD(65, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 880

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

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

GCD(1, 880) = 880 / 880

GCD(1, 880) = 1

GCD of 390, 325, 68, 880 is 1
