Know Least Common Multiple of fractions 31/42, 64/30, 81/244 quickly i.e. 80352 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 31/42, 64/30, 81/244 is 80352.
LCM(31/42, 64/30, 81/244) = 80352
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 31/42,64/30,81/244
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 31,64,81
Least Common Multiple of Numerators i.e. LCM of 31,64,81 is 160704.
GCF of Denominators means GCF of 42,30,244 as per the given fractions.
GCF of 42,30,244 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 31,64,81
Given numbers has no common factors except 1. So, there LCM is their product i.e 160704
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 31,64,81 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,64,81) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,64,81) x common factors =1 x 1 = 1
LCM(31,64,81) = ( 31 × 64 × 81 ) / 1
LCM(31,64,81) = 160704 / 1
LCM(31,64,81) = 160704
Lets's calculate GCF of 42,30,244
2 | 42, 30, 244 |
21, 15, 122 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 160704/2
Therefore the LCM of Fractions 31/42,64/30,81/244 is 80352
