We found the divisors of 40, 434, 153, 606 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 40, 434, 153, 606 is 1.

Therefore, GCD of numbers 40, 434, 153, 606 is 1

Given Input Data is 40, 434, 153, 606

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

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 434 is 2 x 7 x 31

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 606 is 2 x 3 x 101

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(40, 434) = 8680

GCD(40, 434) = ( 40 x 434 ) / 8680

GCD(40, 434) = 17360 / 8680

GCD(40, 434) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 153

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

LCM(2, 153) = 306

GCD(2, 153) = ( 2 x 153 ) / 306

GCD(2, 153) = 306 / 306

GCD(2, 153) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 606

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

LCM(1, 606) = 606

GCD(1, 606) = ( 1 x 606 ) / 606

GCD(1, 606) = 606 / 606

GCD(1, 606) = 1

GCD of 40, 434, 153, 606 is 1
