Know Least Common Multiple of fractions 84/64, 45/11, 28/67, 66/499 quickly i.e. 13860 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 84/64, 45/11, 28/67, 66/499 is 13860.
LCM(84/64, 45/11, 28/67, 66/499) = 13860
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 84/64,45/11,28/67,66/499
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 84,45,28,66
Least Common Multiple of Numerators i.e. LCM of 84,45,28,66 is 13860.
GCF of Denominators means GCF of 64,11,67,499 as per the given fractions.
GCF of 64,11,67,499 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 84,45,28,66
2 | 84, 45, 28, 66 |
2 | 42, 45, 14, 33 |
3 | 21, 45, 7, 33 |
7 | 7, 15, 7, 11 |
1, 15, 1, 11 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 1 x 15 x 1 x 11 = 13860
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 84,45,28,66 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,45,28,66) = 1
common factors(in case of two or more numbers have common factors) = 504
GCF(84,45,28,66) x common factors =1 x 504 = 504
LCM(84,45,28,66) = ( 84 × 45 × 28 × 66 ) / 504
LCM(84,45,28,66) = 6985440 / 504
LCM(84,45,28,66) = 13860
Lets's calculate GCF of 64,11,67,499
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 13860/1
Therefore the LCM of Fractions 84/64,45/11,28/67,66/499 is 13860
