Know Least Common Multiple of fractions 401/91, 658/858 quickly i.e. 263858/13 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 401/91, 658/858 is 263858/13.
LCM(401/91, 658/858) = 263858/13
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 401/91,658/858
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 401,658
Least Common Multiple of Numerators i.e. LCM of 401,658 is 263858.
GCF of Denominators means GCF of 91,858 as per the given fractions.
GCF of 91,858 is 13 as it is the largest common factor for these numbers.
Lets's calculate LCM of 401,658
Given numbers has no common factors except 1. So, there LCM is their product i.e 263858
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 401,658 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(401,658) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(401,658) x common factors =1 x 1 = 1
LCM(401,658) = ( 401 × 658 ) / 1
LCM(401,658) = 263858 / 1
LCM(401,658) = 263858
Lets's calculate GCF of 91,858
13 | 91, 858 |
7, 66 |
∴ So the GCF of the given numbers is 13 = 13
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 263858/13
Therefore the LCM of Fractions 401/91,658/858 is 263858/13
