Know Least Common Multiple of fractions 210/686, 9393/3983 quickly i.e. 93930 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 210/686, 9393/3983 is 93930.
LCM(210/686, 9393/3983) = 93930
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 210/686,9393/3983
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 210,9393
Least Common Multiple of Numerators i.e. LCM of 210,9393 is 657510.
GCF of Denominators means GCF of 686,3983 as per the given fractions.
GCF of 686,3983 is 7 as it is the largest common factor for these numbers.
Lets's calculate LCM of 210,9393
3 | 210, 9393 |
70, 3131 |
∴ So the LCM of the given numbers is 3 x 70 x 3131 = 657510
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 210,9393 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(210,9393) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(210,9393) x common factors =3 x 1 = 3
LCM(210,9393) = ( 210 × 9393 ) / 3
LCM(210,9393) = 1972530 / 3
LCM(210,9393) = 657510
Lets's calculate GCF of 686,3983
7 | 686, 3983 |
98, 569 |
∴ So the GCF of the given numbers is 7 = 7
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 657510/7
Therefore the LCM of Fractions 210/686,9393/3983 is 93930
