Therefore, GCD of numbers 939, 858, 54, 440 is 1

Given Input Data is 939, 858, 54, 440

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

Prime Factorization of 939 is 3 x 313

Prime Factorization of 858 is 2 x 3 x 11 x 13

Prime Factorization of 54 is 2 x 3 x 3 x 3

Prime Factorization of 440 is 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(939, 858) = 268554

GCD(939, 858) = ( 939 x 858 ) / 268554

GCD(939, 858) = 805662 / 268554

GCD(939, 858) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 54

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

LCM(3, 54) = 54

GCD(3, 54) = ( 3 x 54 ) / 54

GCD(3, 54) = 162 / 54

GCD(3, 54) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 440

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

LCM(3, 440) = 1320

GCD(3, 440) = ( 3 x 440 ) / 1320

GCD(3, 440) = 1320 / 1320

GCD(3, 440) = 1

GCD of 939, 858, 54, 440 is 1
