Lets's calculate LCM of 825,864
3 | 825, 864 |
275, 288 |
∴ So the LCM of the given numbers is 3 x 275 x 288 = 237600
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/237600
Therefore, the GCF of Fractions 280/825,4905/864 is 5/237600
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 825,864 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(825,864) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(825,864) x common factors =3 x 1 = 3
LCM(825,864) = ( 825 × 864 ) / 3
LCM(825,864) = 712800 / 3
LCM(825,864) = 237600
