Know Least Common Multiple of fractions 407/871, 668/815 quickly i.e. 271876 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 407/871, 668/815 is 271876.
LCM(407/871, 668/815) = 271876
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 407/871,668/815
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 407,668
Least Common Multiple of Numerators i.e. LCM of 407,668 is 271876.
GCF of Denominators means GCF of 871,815 as per the given fractions.
GCF of 871,815 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 407,668
Given numbers has no common factors except 1. So, there LCM is their product i.e 271876
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 407,668 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(407,668) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(407,668) x common factors =1 x 1 = 1
LCM(407,668) = ( 407 × 668 ) / 1
LCM(407,668) = 271876 / 1
LCM(407,668) = 271876
Lets's calculate GCF of 871,815
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 271876/1
Therefore the LCM of Fractions 407/871,668/815 is 271876
