Therefore, GCD of numbers 578, 986, 45, 545 is 1

Given Input Data is 578, 986, 45, 545

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

Prime Factorization of 578 is 2 x 17 x 17

Prime Factorization of 986 is 2 x 17 x 29

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 545 is 5 x 109

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(578, 986) = 16762

GCD(578, 986) = ( 578 x 986 ) / 16762

GCD(578, 986) = 569908 / 16762

GCD(578, 986) = 34

Step2:

Here we consider the GCD from the above i.e. 34 as first number and the next as 45

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

LCM(34, 45) = 1530

GCD(34, 45) = ( 34 x 45 ) / 1530

GCD(34, 45) = 1530 / 1530

GCD(34, 45) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 545

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

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

GCD(1, 545) = 545 / 545

GCD(1, 545) = 1

GCD of 578, 986, 45, 545 is 1
