Know Least Common Multiple of fractions 1872/128, 8231/830 quickly i.e. 7704216 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 1872/128, 8231/830 is 7704216.
LCM(1872/128, 8231/830) = 7704216
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 1872/128,8231/830
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 1872,8231
Least Common Multiple of Numerators i.e. LCM of 1872,8231 is 15408432.
GCF of Denominators means GCF of 128,830 as per the given fractions.
GCF of 128,830 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 1872,8231
Given numbers has no common factors except 1. So, there LCM is their product i.e 15408432
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 1872,8231 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1872,8231) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(1872,8231) x common factors =1 x 1 = 1
LCM(1872,8231) = ( 1872 × 8231 ) / 1
LCM(1872,8231) = 15408432 / 1
LCM(1872,8231) = 15408432
Lets's calculate GCF of 128,830
2 | 128, 830 |
64, 415 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 15408432/2
Therefore the LCM of Fractions 1872/128,8231/830 is 7704216
