Greatest Common Divisior
We found the divisors of 789, 661, 892, 570 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 789, 661, 892, 570 is 1.
Therefore, GCD of numbers 789, 661, 892, 570 is 1
Given Input Data is 789, 661, 892, 570
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 789 is 3 x 263
Prime Factorization of 661 is 661
Prime Factorization of 892 is 2 x 2 x 223
Prime Factorization of 570 is 2 x 3 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(789, 661) = 521529
GCD(789, 661) = ( 789 x 661 ) / 521529
GCD(789, 661) = 521529 / 521529
GCD(789, 661) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 892
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 892) = 892
GCD(1, 892) = ( 1 x 892 ) / 892
GCD(1, 892) = 892 / 892
GCD(1, 892) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 570
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 570) = 570
GCD(1, 570) = ( 1 x 570 ) / 570
GCD(1, 570) = 570 / 570
GCD(1, 570) = 1
GCD of 789, 661, 892, 570 is 1
