Greatest Common Divisior
We found the divisors of 656, 521, 794, 128 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 656, 521, 794, 128 is 1.
Therefore, GCD of numbers 656, 521, 794, 128 is 1
Given Input Data is 656, 521, 794, 128
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41
Prime Factorization of 521 is 521
Prime Factorization of 794 is 2 x 397
Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2
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(656, 521) = 341776
GCD(656, 521) = ( 656 x 521 ) / 341776
GCD(656, 521) = 341776 / 341776
GCD(656, 521) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 794
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 794) = 794
GCD(1, 794) = ( 1 x 794 ) / 794
GCD(1, 794) = 794 / 794
GCD(1, 794) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 128
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
GCD(1, 128) = 128 / 128
GCD(1, 128) = 1
GCD of 656, 521, 794, 128 is 1
