Know Least Common Multiple of fractions 70/43, 189/68, 165/386 quickly i.e. 20790 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 70/43, 189/68, 165/386 is 20790.
LCM(70/43, 189/68, 165/386) = 20790
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 70/43,189/68,165/386
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 70,189,165
Least Common Multiple of Numerators i.e. LCM of 70,189,165 is 20790.
GCF of Denominators means GCF of 43,68,386 as per the given fractions.
GCF of 43,68,386 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 70,189,165
3 | 70, 189, 165 |
5 | 70, 63, 55 |
7 | 14, 63, 11 |
2, 9, 11 |
∴ So the LCM of the given numbers is 3 x 5 x 7 x 2 x 9 x 11 = 20790
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 70,189,165 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,189,165) = 1
common factors(in case of two or more numbers have common factors) = 105
GCF(70,189,165) x common factors =1 x 105 = 105
LCM(70,189,165) = ( 70 × 189 × 165 ) / 105
LCM(70,189,165) = 2182950 / 105
LCM(70,189,165) = 20790
Lets's calculate GCF of 43,68,386
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 20790/1
Therefore the LCM of Fractions 70/43,189/68,165/386 is 20790
