Greatest Common Divisior
We found the divisors of 797, 770, 90, 860 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 797, 770, 90, 860 is 1.
Therefore, GCD of numbers 797, 770, 90, 860 is 1
Given Input Data is 797, 770, 90, 860
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 797 is 797
Prime Factorization of 770 is 2 x 5 x 7 x 11
Prime Factorization of 90 is 2 x 3 x 3 x 5
Prime Factorization of 860 is 2 x 2 x 5 x 43
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(797, 770) = 613690
GCD(797, 770) = ( 797 x 770 ) / 613690
GCD(797, 770) = 613690 / 613690
GCD(797, 770) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 90
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 90) = 90
GCD(1, 90) = ( 1 x 90 ) / 90
GCD(1, 90) = 90 / 90
GCD(1, 90) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 860
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 860) = 860
GCD(1, 860) = ( 1 x 860 ) / 860
GCD(1, 860) = 860 / 860
GCD(1, 860) = 1
GCD of 797, 770, 90, 860 is 1
