Greatest Common Divisior
We found the divisors of 869, 420, 49, 115 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 869, 420, 49, 115 is 1.
Therefore, GCD of numbers 869, 420, 49, 115 is 1
Given Input Data is 869, 420, 49, 115
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 869 is 11 x 79
Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7
Prime Factorization of 49 is 7 x 7
Prime Factorization of 115 is 5 x 23
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(869, 420) = 364980
GCD(869, 420) = ( 869 x 420 ) / 364980
GCD(869, 420) = 364980 / 364980
GCD(869, 420) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 49
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 49) = 49
GCD(1, 49) = ( 1 x 49 ) / 49
GCD(1, 49) = 49 / 49
GCD(1, 49) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 115
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 115) = 115
GCD(1, 115) = ( 1 x 115 ) / 115
GCD(1, 115) = 115 / 115
GCD(1, 115) = 1
GCD of 869, 420, 49, 115 is 1
