Know Least Common Multiple of fractions 57/791, 23/505, 133/789 quickly i.e. 9177 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 57/791, 23/505, 133/789 is 9177.
LCM(57/791, 23/505, 133/789) = 9177
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 57/791,23/505,133/789
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 57,23,133
Least Common Multiple of Numerators i.e. LCM of 57,23,133 is 9177.
GCF of Denominators means GCF of 791,505,789 as per the given fractions.
GCF of 791,505,789 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 57,23,133
19 | 57, 23, 133 |
3, 23, 7 |
∴ So the LCM of the given numbers is 19 x 3 x 23 x 7 = 9177
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 57,23,133 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,23,133) = 1
common factors(in case of two or more numbers have common factors) = 19
GCF(57,23,133) x common factors =1 x 19 = 19
LCM(57,23,133) = ( 57 × 23 × 133 ) / 19
LCM(57,23,133) = 174363 / 19
LCM(57,23,133) = 9177
Lets's calculate GCF of 791,505,789
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 9177/1
Therefore the LCM of Fractions 57/791,23/505,133/789 is 9177
