Given Input Data is 545, 680, 641, 958

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

Prime Factorization of 545 is 5 x 109

Prime Factorization of 680 is 2 x 2 x 2 x 5 x 17

Prime Factorization of 641 is 641

Prime Factorization of 958 is 2 x 479

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(545, 680) = 74120

GCD(545, 680) = ( 545 x 680 ) / 74120

GCD(545, 680) = 370600 / 74120

GCD(545, 680) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 641

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

LCM(5, 641) = 3205

GCD(5, 641) = ( 5 x 641 ) / 3205

GCD(5, 641) = 3205 / 3205

GCD(5, 641) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 958

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

LCM(1, 958) = 958

GCD(1, 958) = ( 1 x 958 ) / 958

GCD(1, 958) = 958 / 958

GCD(1, 958) = 1

GCD of 545, 680, 641, 958 is 1
