Know Least Common Multiple of fractions 99/90, 55/26, 25/63, 11/969 quickly i.e. 2475 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 99/90, 55/26, 25/63, 11/969 is 2475.
LCM(99/90, 55/26, 25/63, 11/969) = 2475
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 99/90,55/26,25/63,11/969
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 99,55,25,11
Least Common Multiple of Numerators i.e. LCM of 99,55,25,11 is 2475.
GCF of Denominators means GCF of 90,26,63,969 as per the given fractions.
GCF of 90,26,63,969 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 99,55,25,11
5 | 99, 55, 25, 11 |
11 | 99, 11, 5, 11 |
9, 1, 5, 1 |
∴ So the LCM of the given numbers is 5 x 11 x 9 x 1 x 5 x 1 = 2475
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 99,55,25,11 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,55,25,11) = 1
common factors(in case of two or more numbers have common factors) = 605
GCF(99,55,25,11) x common factors =1 x 605 = 605
LCM(99,55,25,11) = ( 99 × 55 × 25 × 11 ) / 605
LCM(99,55,25,11) = 1497375 / 605
LCM(99,55,25,11) = 2475
Lets's calculate GCF of 90,26,63,969
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2475/1
Therefore the LCM of Fractions 99/90,55/26,25/63,11/969 is 2475
