Greatest Common Divisior
We found the divisors of 862, 781, 813, 805 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 862, 781, 813, 805 is 1.
Therefore, GCD of numbers 862, 781, 813, 805 is 1
Given Input Data is 862, 781, 813, 805
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 862 is 2 x 431
Prime Factorization of 781 is 11 x 71
Prime Factorization of 813 is 3 x 271
Prime Factorization of 805 is 5 x 7 x 23
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(862, 781) = 673222
GCD(862, 781) = ( 862 x 781 ) / 673222
GCD(862, 781) = 673222 / 673222
GCD(862, 781) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 813
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
GCD(1, 813) = 813 / 813
GCD(1, 813) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 805
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
GCD(1, 805) = 805 / 805
GCD(1, 805) = 1
GCD of 862, 781, 813, 805 is 1
