Know Least Common Multiple of fractions 45/20, 13/57, 37/81, 13/877 quickly i.e. 21645 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 45/20, 13/57, 37/81, 13/877 is 21645.
LCM(45/20, 13/57, 37/81, 13/877) = 21645
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 45/20,13/57,37/81,13/877
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 45,13,37,13
Least Common Multiple of Numerators i.e. LCM of 45,13,37,13 is 21645.
GCF of Denominators means GCF of 20,57,81,877 as per the given fractions.
GCF of 20,57,81,877 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 45,13,37,13
13 | 45, 13, 37, 13 |
45, 1, 37, 1 |
∴ So the LCM of the given numbers is 13 x 45 x 1 x 37 x 1 = 21645
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 45,13,37,13 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,13,37,13) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(45,13,37,13) x common factors =1 x 13 = 13
LCM(45,13,37,13) = ( 45 × 13 × 37 × 13 ) / 13
LCM(45,13,37,13) = 281385 / 13
LCM(45,13,37,13) = 21645
Lets's calculate GCF of 20,57,81,877
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 21645/1
Therefore the LCM of Fractions 45/20,13/57,37/81,13/877 is 21645
