Know Least Common Multiple of fractions 381/78, 363/441 quickly i.e. 15367 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 381/78, 363/441 is 15367.
LCM(381/78, 363/441) = 15367
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 381/78,363/441
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 381,363
Least Common Multiple of Numerators i.e. LCM of 381,363 is 46101.
GCF of Denominators means GCF of 78,441 as per the given fractions.
GCF of 78,441 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 381,363
3 | 381, 363 |
127, 121 |
∴ So the LCM of the given numbers is 3 x 127 x 121 = 46101
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 381,363 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(381,363) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(381,363) x common factors =3 x 1 = 3
LCM(381,363) = ( 381 × 363 ) / 3
LCM(381,363) = 138303 / 3
LCM(381,363) = 46101
Lets's calculate GCF of 78,441
3 | 78, 441 |
26, 147 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 46101/3
Therefore the LCM of Fractions 381/78,363/441 is 15367
