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 990,810 . The biggest common factor number is the GCF number.
So the greatest common factor 990,810 is 90.
Lets's calculate LCM of 888,902
2 | 888, 902 |
444, 451 |
∴ So the LCM of the given numbers is 2 x 444 x 451 = 400488
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 90/400488
Therefore, the GCF of Fractions 990/888,810/902 is 90/400488
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 888,902 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(888,902) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(888,902) x common factors =2 x 1 = 2
LCM(888,902) = ( 888 × 902 ) / 2
LCM(888,902) = 800976 / 2
LCM(888,902) = 400488
