Greatest Common Divisior
We found the divisors of 860, 643, 146, 878 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 860, 643, 146, 878 is 1.
Therefore, GCD of numbers 860, 643, 146, 878 is 1
Given Input Data is 860, 643, 146, 878
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 860 is 2 x 2 x 5 x 43
Prime Factorization of 643 is 643
Prime Factorization of 146 is 2 x 73
Prime Factorization of 878 is 2 x 439
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(860, 643) = 552980
GCD(860, 643) = ( 860 x 643 ) / 552980
GCD(860, 643) = 552980 / 552980
GCD(860, 643) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 146
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 146) = 146
GCD(1, 146) = ( 1 x 146 ) / 146
GCD(1, 146) = 146 / 146
GCD(1, 146) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 878
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
GCD(1, 878) = 878 / 878
GCD(1, 878) = 1
GCD of 860, 643, 146, 878 is 1
