Least Common Multiple (LCM) of 81/73, 20/63, 41/99 is 66420.
LCM(81/73, 20/63, 41/99) = 66420
LCM of 81/73, 20/63, 41/99
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 81/73,20/63,41/99
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 81,20,41
Least Common Multiple of Numerators i.e. LCM of 81,20,41 is 66420.
GCF of Denominators means GCF of 73,63,99 as per the given fractions.
GCF of 73,63,99 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 81,20,41
LCM of Fractions 81/73,20/63,41/99 is 66420
Given numbers has no common factors except 1. So, there LCM is their product i.e 66420
Least Common Multiple of 81,20,41 with GCF Formula
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 81,20,41 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,20,41) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,20,41) x common factors =1 x 1 = 1
LCM(81,20,41) = ( 81 × 20 × 41 ) / 1
LCM(81,20,41) = 66420 / 1
LCM(81,20,41) = 66420
Lets's calculate GCF of 73,63,99
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 66420/1
Therefore the LCM of Fractions 81/73,20/63,41/99 is 66420
