So the greatest common factor 312,432 is 24.
Lets's calculate LCM of 955,215
5 | 955, 215 |
191, 43 |
∴ So the LCM of the given numbers is 5 x 191 x 43 = 41065
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 24/41065
Therefore, the GCF of Fractions 312/955,432/215 is 24/41065
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 955,215 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(955,215) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(955,215) x common factors =5 x 1 = 5
LCM(955,215) = ( 955 × 215 ) / 5
LCM(955,215) = 205325 / 5
LCM(955,215) = 41065
