Greatest Common Divisior
We found the divisors of 661, 258, 453, 194 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 661, 258, 453, 194 is 1.
Therefore, GCD of numbers 661, 258, 453, 194 is 1
Given Input Data is 661, 258, 453, 194
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 661 is 661
Prime Factorization of 258 is 2 x 3 x 43
Prime Factorization of 453 is 3 x 151
Prime Factorization of 194 is 2 x 97
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(661, 258) = 170538
GCD(661, 258) = ( 661 x 258 ) / 170538
GCD(661, 258) = 170538 / 170538
GCD(661, 258) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 453
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
GCD(1, 453) = 453 / 453
GCD(1, 453) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 194
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 194) = 194
GCD(1, 194) = ( 1 x 194 ) / 194
GCD(1, 194) = 194 / 194
GCD(1, 194) = 1
GCD of 661, 258, 453, 194 is 1
