Know Least Common Multiple of fractions 48/23, 13/51, 15/42, 48/990 quickly i.e. 3120 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 48/23, 13/51, 15/42, 48/990 is 3120.
LCM(48/23, 13/51, 15/42, 48/990) = 3120
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 48/23,13/51,15/42,48/990
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 48,13,15,48
Least Common Multiple of Numerators i.e. LCM of 48,13,15,48 is 3120.
GCF of Denominators means GCF of 23,51,42,990 as per the given fractions.
GCF of 23,51,42,990 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 48,13,15,48
2 | 48, 13, 15, 48 |
2 | 24, 13, 15, 24 |
2 | 12, 13, 15, 12 |
2 | 6, 13, 15, 6 |
3 | 3, 13, 15, 3 |
1, 13, 5, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 1 x 13 x 5 x 1 = 3120
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 48,13,15,48 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(48,13,15,48) = 1
common factors(in case of two or more numbers have common factors) = 144
GCF(48,13,15,48) x common factors =1 x 144 = 144
LCM(48,13,15,48) = ( 48 × 13 × 15 × 48 ) / 144
LCM(48,13,15,48) = 449280 / 144
LCM(48,13,15,48) = 3120
Lets's calculate GCF of 23,51,42,990
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3120/1
Therefore the LCM of Fractions 48/23,13/51,15/42,48/990 is 3120
