Lets's calculate GCF of 831,810
3 | 831, 810 |
277, 270 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 831
:1,3,277,831
Now, list down the factors of 810
:1,2,3,5,6,9,10,15,18,27,30,45,54,81,90,135,162,270,405,810
Greatest Common Factor
We found the factors 831,810 . The biggest common factor number is the GCF number.
So the greatest common factor 831,810 is 3.
Lets's calculate LCM of 661,863
Given numbers has no common factors except 1. So, there LCM is their product i.e 570443
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/570443
Therefore, the GCF of Fractions 831/661,810/863 is 3/570443
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 661,863 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(661,863) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(661,863) x common factors =1 x 1 = 1
LCM(661,863) = ( 661 × 863 ) / 1
LCM(661,863) = 570443 / 1
LCM(661,863) = 570443
