Know Least Common Multiple of fractions 1801/435, 2743/129 quickly i.e. 4940143/3 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 1801/435, 2743/129 is 4940143/3.
LCM(1801/435, 2743/129) = 4940143/3
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 1801/435,2743/129
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 1801,2743
Least Common Multiple of Numerators i.e. LCM of 1801,2743 is 4940143.
GCF of Denominators means GCF of 435,129 as per the given fractions.
GCF of 435,129 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 1801,2743
Given numbers has no common factors except 1. So, there LCM is their product i.e 4940143
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 1801,2743 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1801,2743) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(1801,2743) x common factors =1 x 1 = 1
LCM(1801,2743) = ( 1801 × 2743 ) / 1
LCM(1801,2743) = 4940143 / 1
LCM(1801,2743) = 4940143
Lets's calculate GCF of 435,129
3 | 435, 129 |
145, 43 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4940143/3
Therefore the LCM of Fractions 1801/435,2743/129 is 4940143/3
