Greatest Common Divisior
We found the divisors of 688, 447, 86, 380 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 688, 447, 86, 380 is 1.
Therefore, GCD of numbers 688, 447, 86, 380 is 1
Given Input Data is 688, 447, 86, 380
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43
Prime Factorization of 447 is 3 x 149
Prime Factorization of 86 is 2 x 43
Prime Factorization of 380 is 2 x 2 x 5 x 19
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(688, 447) = 307536
GCD(688, 447) = ( 688 x 447 ) / 307536
GCD(688, 447) = 307536 / 307536
GCD(688, 447) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 86
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 86) = 86
GCD(1, 86) = ( 1 x 86 ) / 86
GCD(1, 86) = 86 / 86
GCD(1, 86) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 380
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 380) = 380
GCD(1, 380) = ( 1 x 380 ) / 380
GCD(1, 380) = 380 / 380
GCD(1, 380) = 1
GCD of 688, 447, 86, 380 is 1
