Lets's calculate LCM of 444,666
2 | 444, 666 |
3 | 222, 333 |
37 | 74, 111 |
2, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 37 x 2 x 3 = 1332
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1332
Therefore, the GCF of Fractions 858/444,873/666 is 3/1332
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 444,666 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(444,666) = 222
common factors(in case of two or more numbers have common factors) = 1
GCF(444,666) x common factors =222 x 1 = 222
LCM(444,666) = ( 444 × 666 ) / 222
LCM(444,666) = 295704 / 222
LCM(444,666) = 1332
