Greatest Common Divisior
We found the divisors of 721, 159, 974, 657 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 721, 159, 974, 657 is 1.
Therefore, GCD of numbers 721, 159, 974, 657 is 1
Given Input Data is 721, 159, 974, 657
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 721 is 7 x 103
Prime Factorization of 159 is 3 x 53
Prime Factorization of 974 is 2 x 487
Prime Factorization of 657 is 3 x 3 x 73
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(721, 159) = 114639
GCD(721, 159) = ( 721 x 159 ) / 114639
GCD(721, 159) = 114639 / 114639
GCD(721, 159) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 974
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 974) = 974
GCD(1, 974) = ( 1 x 974 ) / 974
GCD(1, 974) = 974 / 974
GCD(1, 974) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 657
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
GCD(1, 657) = 657 / 657
GCD(1, 657) = 1
GCD of 721, 159, 974, 657 is 1
