Know Least Common Multiple of fractions 720/858, 1144/688 quickly i.e. 51480 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 720/858, 1144/688 is 51480.
LCM(720/858, 1144/688) = 51480
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 720/858,1144/688
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 720,1144
Least Common Multiple of Numerators i.e. LCM of 720,1144 is 102960.
GCF of Denominators means GCF of 858,688 as per the given fractions.
GCF of 858,688 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 720,1144
2 | 720, 1144 |
2 | 360, 572 |
2 | 180, 286 |
90, 143 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 90 x 143 = 102960
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 720,1144 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(720,1144) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(720,1144) x common factors =8 x 1 = 8
LCM(720,1144) = ( 720 × 1144 ) / 8
LCM(720,1144) = 823680 / 8
LCM(720,1144) = 102960
Lets's calculate GCF of 858,688
2 | 858, 688 |
429, 344 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 102960/2
Therefore the LCM of Fractions 720/858,1144/688 is 51480
