Therefore, GCD of numbers 425, 850, 388, 666 is 1

Given Input Data is 425, 850, 388, 666

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

Prime Factorization of 425 is 5 x 5 x 17

Prime Factorization of 850 is 2 x 5 x 5 x 17

Prime Factorization of 388 is 2 x 2 x 97

Prime Factorization of 666 is 2 x 3 x 3 x 37

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(425, 850) = 850

GCD(425, 850) = ( 425 x 850 ) / 850

GCD(425, 850) = 361250 / 850

GCD(425, 850) = 425

Step2:

Here we consider the GCD from the above i.e. 425 as first number and the next as 388

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

LCM(425, 388) = 164900

GCD(425, 388) = ( 425 x 388 ) / 164900

GCD(425, 388) = 164900 / 164900

GCD(425, 388) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 666

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

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

GCD(1, 666) = 666 / 666

GCD(1, 666) = 1

GCD of 425, 850, 388, 666 is 1
