Lets's calculate LCM of 312,882
2 | 312, 882 |
3 | 156, 441 |
52, 147 |
∴ So the LCM of the given numbers is 2 x 3 x 52 x 147 = 45864
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/45864
Therefore, the GCF of Fractions 781/312,663/882 is 1/45864
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 312,882 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(312,882) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(312,882) x common factors =6 x 1 = 6
LCM(312,882) = ( 312 × 882 ) / 6
LCM(312,882) = 275184 / 6
LCM(312,882) = 45864
