Greatest Common Divisior
We found the divisors of 855, 613, 744, 455 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 855, 613, 744, 455 is 1.
Therefore, GCD of numbers 855, 613, 744, 455 is 1
Given Input Data is 855, 613, 744, 455
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 855 is 3 x 3 x 5 x 19
Prime Factorization of 613 is 613
Prime Factorization of 744 is 2 x 2 x 2 x 3 x 31
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(855, 613) = 524115
GCD(855, 613) = ( 855 x 613 ) / 524115
GCD(855, 613) = 524115 / 524115
GCD(855, 613) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 744
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 744) = 744
GCD(1, 744) = ( 1 x 744 ) / 744
GCD(1, 744) = 744 / 744
GCD(1, 744) = 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 855, 613, 744, 455 is 1
