Lets's calculate GCF of 834,405
3 | 834, 405 |
278, 135 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 834
:1,2,3,6,139,278,417,834
Now, list down the factors of 405
:1,3,5,9,15,27,45,81,135,405
Greatest Common Factor
We found the factors 834,405 . The biggest common factor number is the GCF number.
So the greatest common factor 834,405 is 3.
Lets's calculate LCM of 402,805
Given numbers has no common factors except 1. So, there LCM is their product i.e 323610
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/323610
Therefore, the GCF of Fractions 834/402,405/805 is 3/323610
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 402,805 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(402,805) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(402,805) x common factors =1 x 1 = 1
LCM(402,805) = ( 402 × 805 ) / 1
LCM(402,805) = 323610 / 1
LCM(402,805) = 323610
