Lets's calculate LCM of 840,3327
3 | 840, 3327 |
280, 1109 |
∴ So the LCM of the given numbers is 3 x 280 x 1109 = 931560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/931560
Therefore, the GCF of Fractions 70/840,2931/3327 is 1/931560
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 840,3327 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(840,3327) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(840,3327) x common factors =3 x 1 = 3
LCM(840,3327) = ( 840 × 3327 ) / 3
LCM(840,3327) = 2794680 / 3
LCM(840,3327) = 931560
