Greatest Common Divisior
We found the divisors of 986, 209, 65, 784 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 986, 209, 65, 784 is 1.
Therefore, GCD of numbers 986, 209, 65, 784 is 1
Given Input Data is 986, 209, 65, 784
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 986 is 2 x 17 x 29
Prime Factorization of 209 is 11 x 19
Prime Factorization of 65 is 5 x 13
Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7
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(986, 209) = 206074
GCD(986, 209) = ( 986 x 209 ) / 206074
GCD(986, 209) = 206074 / 206074
GCD(986, 209) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 65
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
GCD(1, 65) = 65 / 65
GCD(1, 65) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 784
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
GCD(1, 784) = 784 / 784
GCD(1, 784) = 1
GCD of 986, 209, 65, 784 is 1
