Greatest Common Divisior
We found the divisors of 878, 665, 45, 742 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 878, 665, 45, 742 is 1.
Therefore, GCD of numbers 878, 665, 45, 742 is 1
Given Input Data is 878, 665, 45, 742
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 878 is 2 x 439
Prime Factorization of 665 is 5 x 7 x 19
Prime Factorization of 45 is 3 x 3 x 5
Prime Factorization of 742 is 2 x 7 x 53
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(878, 665) = 583870
GCD(878, 665) = ( 878 x 665 ) / 583870
GCD(878, 665) = 583870 / 583870
GCD(878, 665) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 45
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 45) = 45
GCD(1, 45) = ( 1 x 45 ) / 45
GCD(1, 45) = 45 / 45
GCD(1, 45) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 742
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 742) = 742
GCD(1, 742) = ( 1 x 742 ) / 742
GCD(1, 742) = 742 / 742
GCD(1, 742) = 1
GCD of 878, 665, 45, 742 is 1
