Know Least Common Multiple of fractions 721/13, 431/3536 quickly i.e. 310751/13 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 721/13, 431/3536 is 310751/13.
LCM(721/13, 431/3536) = 310751/13
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 721/13,431/3536
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 721,431
Least Common Multiple of Numerators i.e. LCM of 721,431 is 310751.
GCF of Denominators means GCF of 13,3536 as per the given fractions.
GCF of 13,3536 is 13 as it is the largest common factor for these numbers.
Lets's calculate LCM of 721,431
Given numbers has no common factors except 1. So, there LCM is their product i.e 310751
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 721,431 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(721,431) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(721,431) x common factors =1 x 1 = 1
LCM(721,431) = ( 721 × 431 ) / 1
LCM(721,431) = 310751 / 1
LCM(721,431) = 310751
Lets's calculate GCF of 13,3536
13 | 13, 3536 |
1, 272 |
∴ So the GCF of the given numbers is 13 = 13
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 310751/13
Therefore the LCM of Fractions 721/13,431/3536 is 310751/13
