1, 719
Greatest Common Divisior
We found the divisors of 861, 685, 654, 719 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 861, 685, 654, 719 is 1.
Therefore, GCD of numbers 861, 685, 654, 719 is 1
Given Input Data is 861, 685, 654, 719
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 861 is 3 x 7 x 41
Prime Factorization of 685 is 5 x 137
Prime Factorization of 654 is 2 x 3 x 109
Prime Factorization of 719 is 719
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(861, 685) = 589785
GCD(861, 685) = ( 861 x 685 ) / 589785
GCD(861, 685) = 589785 / 589785
GCD(861, 685) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 654
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
GCD(1, 654) = 654 / 654
GCD(1, 654) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 719
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 719) = 719
GCD(1, 719) = ( 1 x 719 ) / 719
GCD(1, 719) = 719 / 719
GCD(1, 719) = 1
GCD of 861, 685, 654, 719 is 1
