Know Least Common Multiple of fractions 31/721, 68/961, 667/385 quickly i.e. 1406036 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 31/721, 68/961, 667/385 is 1406036.
LCM(31/721, 68/961, 667/385) = 1406036
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 31/721,68/961,667/385
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 31,68,667
Least Common Multiple of Numerators i.e. LCM of 31,68,667 is 1406036.
GCF of Denominators means GCF of 721,961,385 as per the given fractions.
GCF of 721,961,385 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 31,68,667
Given numbers has no common factors except 1. So, there LCM is their product i.e 1406036
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 31,68,667 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,68,667) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,68,667) x common factors =1 x 1 = 1
LCM(31,68,667) = ( 31 × 68 × 667 ) / 1
LCM(31,68,667) = 1406036 / 1
LCM(31,68,667) = 1406036
Lets's calculate GCF of 721,961,385
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1406036/1
Therefore the LCM of Fractions 31/721,68/961,667/385 is 1406036
