Lets's calculate LCM of 399,987
3 | 399, 987 |
7 | 133, 329 |
19, 47 |
∴ So the LCM of the given numbers is 3 x 7 x 19 x 47 = 18753
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18753
Therefore, the GCF of Fractions 826/399,243/987 is 1/18753
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 399,987 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(399,987) = 21
common factors(in case of two or more numbers have common factors) = 1
GCF(399,987) x common factors =21 x 1 = 21
LCM(399,987) = ( 399 × 987 ) / 21
LCM(399,987) = 393813 / 21
LCM(399,987) = 18753
