Know Least Common Multiple of fractions 434/247, 1856/409 quickly i.e. 402752 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 434/247, 1856/409 is 402752.
LCM(434/247, 1856/409) = 402752
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 434/247,1856/409
Formula to find LCM of Fractions is
LCM = LCM of Numerators/GCF of Denominators
As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators
In the given fractions LCM of Numerators means LCM of 434,1856
Least Common Multiple of Numerators i.e. LCM of 434,1856 is 402752.
GCF of Denominators means GCF of 247,409 as per the given fractions.
GCF of 247,409 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 434,1856
2 | 434, 1856 |
217, 928 |
∴ So the LCM of the given numbers is 2 x 217 x 928 = 402752
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 434,1856 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(434,1856) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(434,1856) x common factors =2 x 1 = 2
LCM(434,1856) = ( 434 × 1856 ) / 2
LCM(434,1856) = 805504 / 2
LCM(434,1856) = 402752
Lets's calculate GCF of 247,409
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 402752/1
Therefore the LCM of Fractions 434/247,1856/409 is 402752
