Know Least Common Multiple of fractions 400/69, 378/3841 quickly i.e. 75600/23 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 400/69, 378/3841 is 75600/23.
LCM(400/69, 378/3841) = 75600/23
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 400/69,378/3841
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 400,378
Least Common Multiple of Numerators i.e. LCM of 400,378 is 75600.
GCF of Denominators means GCF of 69,3841 as per the given fractions.
GCF of 69,3841 is 23 as it is the largest common factor for these numbers.
Lets's calculate LCM of 400,378
2 | 400, 378 |
200, 189 |
∴ So the LCM of the given numbers is 2 x 200 x 189 = 75600
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 400,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(400,378) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(400,378) x common factors =2 x 1 = 2
LCM(400,378) = ( 400 × 378 ) / 2
LCM(400,378) = 151200 / 2
LCM(400,378) = 75600
Lets's calculate GCF of 69,3841
23 | 69, 3841 |
3, 167 |
∴ So the GCF of the given numbers is 23 = 23
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 75600/23
Therefore the LCM of Fractions 400/69,378/3841 is 75600/23
