1, 691
Greatest Common Divisior
We found the divisors of 384, 651, 40, 691 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 384, 651, 40, 691 is 1.
Therefore, GCD of numbers 384, 651, 40, 691 is 1
Given Input Data is 384, 651, 40, 691
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 384 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3
Prime Factorization of 651 is 3 x 7 x 31
Prime Factorization of 40 is 2 x 2 x 2 x 5
Prime Factorization of 691 is 691
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(384, 651) = 83328
GCD(384, 651) = ( 384 x 651 ) / 83328
GCD(384, 651) = 249984 / 83328
GCD(384, 651) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 40
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 40) = 120
GCD(3, 40) = ( 3 x 40 ) / 120
GCD(3, 40) = 120 / 120
GCD(3, 40) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 691
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
GCD(1, 691) = 691 / 691
GCD(1, 691) = 1
GCD of 384, 651, 40, 691 is 1
