Know Least Common Multiple of fractions 128/16, 660/6812 quickly i.e. 5280 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 128/16, 660/6812 is 5280.
LCM(128/16, 660/6812) = 5280
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 128/16,660/6812
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 128,660
Least Common Multiple of Numerators i.e. LCM of 128,660 is 21120.
GCF of Denominators means GCF of 16,6812 as per the given fractions.
GCF of 16,6812 is 4 as it is the largest common factor for these numbers.
Lets's calculate LCM of 128,660
2 | 128, 660 |
2 | 64, 330 |
32, 165 |
∴ So the LCM of the given numbers is 2 x 2 x 32 x 165 = 21120
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 128,660 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(128,660) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(128,660) x common factors =4 x 1 = 4
LCM(128,660) = ( 128 × 660 ) / 4
LCM(128,660) = 84480 / 4
LCM(128,660) = 21120
Lets's calculate GCF of 16,6812
2 | 16, 6812 |
2 | 8, 3406 |
4, 1703 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 21120/4
Therefore the LCM of Fractions 128/16,660/6812 is 5280
