Greatest Common Divisior
We found the divisors of 641, 462, 457, 343 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 641, 462, 457, 343 is 1.
Therefore, GCD of numbers 641, 462, 457, 343 is 1
Given Input Data is 641, 462, 457, 343
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 641 is 641
Prime Factorization of 462 is 2 x 3 x 7 x 11
Prime Factorization of 457 is 457
Prime Factorization of 343 is 7 x 7 x 7
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(641, 462) = 296142
GCD(641, 462) = ( 641 x 462 ) / 296142
GCD(641, 462) = 296142 / 296142
GCD(641, 462) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 457
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
GCD(1, 457) = 457 / 457
GCD(1, 457) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 343
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 343) = 343
GCD(1, 343) = ( 1 x 343 ) / 343
GCD(1, 343) = 343 / 343
GCD(1, 343) = 1
GCD of 641, 462, 457, 343 is 1
