So the greatest common factor 670,558 is 2.
Lets's calculate LCM of 398,910
2 | 398, 910 |
199, 455 |
∴ So the LCM of the given numbers is 2 x 199 x 455 = 181090
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/181090
Therefore, the GCF of Fractions 670/398,558/910 is 2/181090
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 398,910 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(398,910) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(398,910) x common factors =2 x 1 = 2
LCM(398,910) = ( 398 × 910 ) / 2
LCM(398,910) = 362180 / 2
LCM(398,910) = 181090
