Make use of GCD Calculator to determine the Greatest Common Divisor of 831, 942, 815 i.e. 1 largest integer that divides all the numbers equally.
GCD of 831, 942, 815 is 1
GCD(831, 942, 815) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 831, 942, 815 is 1
GCD(831, 942, 815) = 1
Given Input numbers are 831, 942, 815
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 163, 815
Greatest Common Divisior
We found the divisors of 831, 942, 815 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 831, 942, 815 is 1.
Therefore, GCD of numbers 831, 942, 815 is 1
Given Input Data is 831, 942, 815
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 831 is 3 x 277
Prime Factorization of 942 is 2 x 3 x 157
Prime Factorization of 815 is 5 x 163
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(831, 942) = 260934
GCD(831, 942) = ( 831 x 942 ) / 260934
GCD(831, 942) = 782802 / 260934
GCD(831, 942) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 815
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 815) = 2445
GCD(3, 815) = ( 3 x 815 ) / 2445
GCD(3, 815) = 2445 / 2445
GCD(3, 815) = 1
GCD of 831, 942, 815 is 1
