Lets's calculate LCM of 308,238
2 | 308, 238 |
7 | 154, 119 |
22, 17 |
∴ So the LCM of the given numbers is 2 x 7 x 22 x 17 = 5236
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/5236
Therefore, the GCF of Fractions 247/308,585/238 is 13/5236
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 308,238 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(308,238) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(308,238) x common factors =14 x 1 = 14
LCM(308,238) = ( 308 × 238 ) / 14
LCM(308,238) = 73304 / 14
LCM(308,238) = 5236
