Greatest Common Divisior
We found the divisors of 859, 655, 965, 390 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 859, 655, 965, 390 is 1.
Therefore, GCD of numbers 859, 655, 965, 390 is 1
Given Input Data is 859, 655, 965, 390
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 859 is 859
Prime Factorization of 655 is 5 x 131
Prime Factorization of 965 is 5 x 193
Prime Factorization of 390 is 2 x 3 x 5 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(859, 655) = 562645
GCD(859, 655) = ( 859 x 655 ) / 562645
GCD(859, 655) = 562645 / 562645
GCD(859, 655) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 965
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
GCD(1, 965) = 965 / 965
GCD(1, 965) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 390
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
GCD(1, 390) = 390 / 390
GCD(1, 390) = 1
GCD of 859, 655, 965, 390 is 1
