Lets's calculate LCM of 93,2217
3 | 93, 2217 |
31, 739 |
∴ So the LCM of the given numbers is 3 x 31 x 739 = 68727
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/68727
Therefore, the GCF of Fractions 308/93,684/2217 is 4/68727
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 93,2217 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(93,2217) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(93,2217) x common factors =3 x 1 = 3
LCM(93,2217) = ( 93 × 2217 ) / 3
LCM(93,2217) = 206181 / 3
LCM(93,2217) = 68727
