Know Least Common Multiple of fractions 23/71, 61/13, 57/143 quickly i.e. 79971 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 23/71, 61/13, 57/143 is 79971.
LCM(23/71, 61/13, 57/143) = 79971
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 23/71,61/13,57/143
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 23,61,57
Least Common Multiple of Numerators i.e. LCM of 23,61,57 is 79971.
GCF of Denominators means GCF of 71,13,143 as per the given fractions.
GCF of 71,13,143 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 23,61,57
Given numbers has no common factors except 1. So, there LCM is their product i.e 79971
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 23,61,57 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,61,57) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(23,61,57) x common factors =1 x 1 = 1
LCM(23,61,57) = ( 23 × 61 × 57 ) / 1
LCM(23,61,57) = 79971 / 1
LCM(23,61,57) = 79971
Lets's calculate GCF of 71,13,143
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 79971/1
Therefore the LCM of Fractions 23/71,61/13,57/143 is 79971
