Know Least Common Multiple of fractions 128/33, 1640/147 quickly i.e. 26240/3 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 128/33, 1640/147 is 26240/3.
LCM(128/33, 1640/147) = 26240/3
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 128/33,1640/147
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 128,1640
Least Common Multiple of Numerators i.e. LCM of 128,1640 is 26240.
GCF of Denominators means GCF of 33,147 as per the given fractions.
GCF of 33,147 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 128,1640
2 | 128, 1640 |
2 | 64, 820 |
2 | 32, 410 |
16, 205 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 16 x 205 = 26240
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 128,1640 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(128,1640) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(128,1640) x common factors =8 x 1 = 8
LCM(128,1640) = ( 128 × 1640 ) / 8
LCM(128,1640) = 209920 / 8
LCM(128,1640) = 26240
Lets's calculate GCF of 33,147
3 | 33, 147 |
11, 49 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 26240/3
Therefore the LCM of Fractions 128/33,1640/147 is 26240/3
