Lets's calculate LCM of 434,490
2 | 434, 490 |
7 | 217, 245 |
31, 35 |
∴ So the LCM of the given numbers is 2 x 7 x 31 x 35 = 15190
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/15190
Therefore, the GCF of Fractions 644/434,266/490 is 14/15190
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 434,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(434,490) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(434,490) x common factors =14 x 1 = 14
LCM(434,490) = ( 434 × 490 ) / 14
LCM(434,490) = 212660 / 14
LCM(434,490) = 15190
