Greatest Common Divisior

We found the divisors of 407, 805, 402, 683 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 407, 805, 402, 683 is 1.

Therefore, GCD of numbers 407, 805, 402, 683 is 1

Given Input Data is 407, 805, 402, 683

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

Prime Factorization of 407 is 11 x 37

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 683 is 683

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(407, 805) = 327635

GCD(407, 805) = ( 407 x 805 ) / 327635

GCD(407, 805) = 327635 / 327635

GCD(407, 805) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 402

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

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

GCD(1, 402) = 402 / 402

GCD(1, 402) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 683

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

LCM(1, 683) = 683

GCD(1, 683) = ( 1 x 683 ) / 683

GCD(1, 683) = 683 / 683

GCD(1, 683) = 1

GCD of 407, 805, 402, 683 is 1
