Lets's calculate LCM of 638,870
2 | 638, 870 |
29 | 319, 435 |
11, 15 |
∴ So the LCM of the given numbers is 2 x 29 x 11 x 15 = 9570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/9570
Therefore, the GCF of Fractions 903/638,159/870 is 3/9570
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 638,870 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(638,870) = 58
common factors(in case of two or more numbers have common factors) = 1
GCF(638,870) x common factors =58 x 1 = 58
LCM(638,870) = ( 638 × 870 ) / 58
LCM(638,870) = 555060 / 58
LCM(638,870) = 9570
