Greatest Common Divisior
We found the divisors of 860, 809, 99, 655 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 860, 809, 99, 655 is 1.
Therefore, GCD of numbers 860, 809, 99, 655 is 1
Given Input Data is 860, 809, 99, 655
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 809 is 809
Prime Factorization of 99 is 3 x 3 x 11
Prime Factorization of 655 is 5 x 131
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, 809) = 695740
GCD(860, 809) = ( 860 x 809 ) / 695740
GCD(860, 809) = 695740 / 695740
GCD(860, 809) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 99
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 99) = 99
GCD(1, 99) = ( 1 x 99 ) / 99
GCD(1, 99) = 99 / 99
GCD(1, 99) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 655
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
GCD(1, 655) = 655 / 655
GCD(1, 655) = 1
GCD of 860, 809, 99, 655 is 1
