Lets's calculate LCM of 768,3141
3 | 768, 3141 |
256, 1047 |
∴ So the LCM of the given numbers is 3 x 256 x 1047 = 804096
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/804096
Therefore, the GCF of Fractions 324/768,7090/3141 is 2/804096
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 768,3141 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(768,3141) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(768,3141) x common factors =3 x 1 = 3
LCM(768,3141) = ( 768 × 3141 ) / 3
LCM(768,3141) = 2412288 / 3
LCM(768,3141) = 804096
