Greatest Common Divisior
We found the divisors of 247, 991, 470 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 247, 991, 470 is 1.
Therefore, GCD of numbers 247, 991, 470 is 1
Given Input Data is 247, 991, 470
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 247 is 13 x 19
Prime Factorization of 991 is 991
Prime Factorization of 470 is 2 x 5 x 47
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(247, 991) = 244777
GCD(247, 991) = ( 247 x 991 ) / 244777
GCD(247, 991) = 244777 / 244777
GCD(247, 991) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 470
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 470) = 470
GCD(1, 470) = ( 1 x 470 ) / 470
GCD(1, 470) = 470 / 470
GCD(1, 470) = 1
GCD of 247, 991, 470 is 1
