Know Least Common Multiple of fractions 990/42, 140/6518 quickly i.e. 6930 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 990/42, 140/6518 is 6930.
LCM(990/42, 140/6518) = 6930
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 990/42,140/6518
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 990,140
Least Common Multiple of Numerators i.e. LCM of 990,140 is 13860.
GCF of Denominators means GCF of 42,6518 as per the given fractions.
GCF of 42,6518 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 990,140
2 | 990, 140 |
5 | 495, 70 |
99, 14 |
∴ So the LCM of the given numbers is 2 x 5 x 99 x 14 = 13860
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 990,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(990,140) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(990,140) x common factors =10 x 1 = 10
LCM(990,140) = ( 990 × 140 ) / 10
LCM(990,140) = 138600 / 10
LCM(990,140) = 13860
Lets's calculate GCF of 42,6518
2 | 42, 6518 |
21, 3259 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 13860/2
Therefore the LCM of Fractions 990/42,140/6518 is 6930
