Know Least Common Multiple of fractions 720/27, 147/45, 144/35 quickly i.e. 35280 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 720/27, 147/45, 144/35 is 35280.
LCM(720/27, 147/45, 144/35) = 35280
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 720/27,147/45,144/35
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 720,147,144
Least Common Multiple of Numerators i.e. LCM of 720,147,144 is 35280.
GCF of Denominators means GCF of 27,45,35 as per the given fractions.
GCF of 27,45,35 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 720,147,144
2 | 720, 147, 144 |
2 | 360, 147, 72 |
2 | 180, 147, 36 |
2 | 90, 147, 18 |
3 | 45, 147, 9 |
3 | 15, 49, 3 |
5, 49, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 3 x 5 x 49 x 1 = 35280
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 720,147,144 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(720,147,144) = 3
common factors(in case of two or more numbers have common factors) = 144
GCF(720,147,144) x common factors =3 x 144 = 432
LCM(720,147,144) = ( 720 × 147 × 144 ) / 432
LCM(720,147,144) = 15240960 / 432
LCM(720,147,144) = 35280
Lets's calculate GCF of 27,45,35
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 35280/1
Therefore the LCM of Fractions 720/27,147/45,144/35 is 35280
