Know Least Common Multiple of fractions 28/33, 99/87, 285/135 quickly i.e. 87780 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 28/33, 99/87, 285/135 is 87780.
LCM(28/33, 99/87, 285/135) = 87780
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 28/33,99/87,285/135
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 28,99,285
Least Common Multiple of Numerators i.e. LCM of 28,99,285 is 263340.
GCF of Denominators means GCF of 33,87,135 as per the given fractions.
GCF of 33,87,135 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 28,99,285
3 | 28, 99, 285 |
28, 33, 95 |
∴ So the LCM of the given numbers is 3 x 28 x 33 x 95 = 263340
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 28,99,285 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,99,285) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(28,99,285) x common factors =1 x 3 = 3
LCM(28,99,285) = ( 28 × 99 × 285 ) / 3
LCM(28,99,285) = 790020 / 3
LCM(28,99,285) = 263340
Lets's calculate GCF of 33,87,135
3 | 33, 87, 135 |
11, 29, 45 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 263340/3
Therefore the LCM of Fractions 28/33,99/87,285/135 is 87780
