So the greatest common factor 199,840 is 1.
Lets's calculate LCM of 783,928
29 | 783, 928 |
27, 32 |
∴ So the LCM of the given numbers is 29 x 27 x 32 = 25056
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25056
Therefore, the GCF of Fractions 199/783,840/928 is 1/25056
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 783,928 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(783,928) = 29
common factors(in case of two or more numbers have common factors) = 1
GCF(783,928) x common factors =29 x 1 = 29
LCM(783,928) = ( 783 × 928 ) / 29
LCM(783,928) = 726624 / 29
LCM(783,928) = 25056
