So the greatest common factor 108,918 is 54.
Lets's calculate LCM of 810,117
3 | 810, 117 |
3 | 270, 39 |
90, 13 |
∴ So the LCM of the given numbers is 3 x 3 x 90 x 13 = 10530
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 54/10530
Therefore, the GCF of Fractions 108/810,918/117 is 54/10530
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 810,117 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(810,117) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(810,117) x common factors =9 x 1 = 9
LCM(810,117) = ( 810 × 117 ) / 9
LCM(810,117) = 94770 / 9
LCM(810,117) = 10530
