We found the divisors of 445, 412, 43, 455 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 445, 412, 43, 455 is 1.

Therefore, GCD of numbers 445, 412, 43, 455 is 1

Given Input Data is 445, 412, 43, 455

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

Prime Factorization of 445 is 5 x 89

Prime Factorization of 412 is 2 x 2 x 103

Prime Factorization of 43 is 43

Prime Factorization of 455 is 5 x 7 x 13

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(445, 412) = 183340

GCD(445, 412) = ( 445 x 412 ) / 183340

GCD(445, 412) = 183340 / 183340

GCD(445, 412) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 43

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

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

GCD(1, 43) = 43 / 43

GCD(1, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 455

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

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

GCD(1, 455) = 455 / 455

GCD(1, 455) = 1

GCD of 445, 412, 43, 455 is 1
