Lets's calculate LCM of 884,387,261
3 | 884, 387, 261 |
3 | 884, 129, 87 |
884, 43, 29 |
∴ So the LCM of the given numbers is 3 x 3 x 884 x 43 x 29 = 9921132
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/9921132
Therefore, the GCF of Fractions 28/884,721/387,392/261 is 7/9921132
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 884,387,261 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(884,387,261) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(884,387,261) x common factors =1 x 9 = 9
LCM(884,387,261) = ( 884 × 387 × 261 ) / 9
LCM(884,387,261) = 89290188 / 9
LCM(884,387,261) = 9921132
