Know Least Common Multiple of fractions 73/12, 47/85, 79/981 quickly i.e. 271049 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 73/12, 47/85, 79/981 is 271049.
LCM(73/12, 47/85, 79/981) = 271049
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 73/12,47/85,79/981
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 73,47,79
Least Common Multiple of Numerators i.e. LCM of 73,47,79 is 271049.
GCF of Denominators means GCF of 12,85,981 as per the given fractions.
GCF of 12,85,981 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 73,47,79
Given numbers has no common factors except 1. So, there LCM is their product i.e 271049
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 73,47,79 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(73,47,79) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(73,47,79) x common factors =1 x 1 = 1
LCM(73,47,79) = ( 73 × 47 × 79 ) / 1
LCM(73,47,79) = 271049 / 1
LCM(73,47,79) = 271049
Lets's calculate GCF of 12,85,981
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 271049/1
Therefore the LCM of Fractions 73/12,47/85,79/981 is 271049
