Given Input Data is 435, 305, 672, 193

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

Prime Factorization of 435 is 3 x 5 x 29

Prime Factorization of 305 is 5 x 61

Prime Factorization of 672 is 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime Factorization of 193 is 193

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(435, 305) = 26535

GCD(435, 305) = ( 435 x 305 ) / 26535

GCD(435, 305) = 132675 / 26535

GCD(435, 305) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 672

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

LCM(5, 672) = 3360

GCD(5, 672) = ( 5 x 672 ) / 3360

GCD(5, 672) = 3360 / 3360

GCD(5, 672) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 193

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

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

GCD(1, 193) = 193 / 193

GCD(1, 193) = 1

GCD of 435, 305, 672, 193 is 1
