Know Least Common Multiple of fractions 40/288, 3172/3922 quickly i.e. 15860 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 40/288, 3172/3922 is 15860.
LCM(40/288, 3172/3922) = 15860
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 40/288,3172/3922
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 40,3172
Least Common Multiple of Numerators i.e. LCM of 40,3172 is 31720.
GCF of Denominators means GCF of 288,3922 as per the given fractions.
GCF of 288,3922 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 40,3172
2 | 40, 3172 |
2 | 20, 1586 |
10, 793 |
∴ So the LCM of the given numbers is 2 x 2 x 10 x 793 = 31720
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 40,3172 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,3172) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(40,3172) x common factors =4 x 1 = 4
LCM(40,3172) = ( 40 × 3172 ) / 4
LCM(40,3172) = 126880 / 4
LCM(40,3172) = 31720
Lets's calculate GCF of 288,3922
2 | 288, 3922 |
144, 1961 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 31720/2
Therefore the LCM of Fractions 40/288,3172/3922 is 15860
