Know Least Common Multiple of fractions 100/715, 3942/331 quickly i.e. 197100 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 100/715, 3942/331 is 197100.
LCM(100/715, 3942/331) = 197100
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 100/715,3942/331
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 100,3942
Least Common Multiple of Numerators i.e. LCM of 100,3942 is 197100.
GCF of Denominators means GCF of 715,331 as per the given fractions.
GCF of 715,331 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 100,3942
2 | 100, 3942 |
50, 1971 |
∴ So the LCM of the given numbers is 2 x 50 x 1971 = 197100
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 100,3942 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(100,3942) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(100,3942) x common factors =2 x 1 = 2
LCM(100,3942) = ( 100 × 3942 ) / 2
LCM(100,3942) = 394200 / 2
LCM(100,3942) = 197100
Lets's calculate GCF of 715,331
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 197100/1
Therefore the LCM of Fractions 100/715,3942/331 is 197100
