So the greatest common factor 424,280 is 8.
Lets's calculate LCM of 910,838
2 | 910, 838 |
455, 419 |
∴ So the LCM of the given numbers is 2 x 455 x 419 = 381290
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/381290
Therefore, the GCF of Fractions 424/910,280/838 is 8/381290
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 910,838 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(910,838) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(910,838) x common factors =2 x 1 = 2
LCM(910,838) = ( 910 × 838 ) / 2
LCM(910,838) = 762580 / 2
LCM(910,838) = 381290
