Know Least Common Multiple of fractions 378/831, 722/733 quickly i.e. 136458 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 378/831, 722/733 is 136458.
LCM(378/831, 722/733) = 136458
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 378/831,722/733
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 378,722
Least Common Multiple of Numerators i.e. LCM of 378,722 is 136458.
GCF of Denominators means GCF of 831,733 as per the given fractions.
GCF of 831,733 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 378,722
2 | 378, 722 |
189, 361 |
∴ So the LCM of the given numbers is 2 x 189 x 361 = 136458
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 378,722 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(378,722) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(378,722) x common factors =2 x 1 = 2
LCM(378,722) = ( 378 × 722 ) / 2
LCM(378,722) = 272916 / 2
LCM(378,722) = 136458
Lets's calculate GCF of 831,733
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 136458/1
Therefore the LCM of Fractions 378/831,722/733 is 136458
