Know Least Common Multiple of fractions 78/57, 11/58, 84/89, 88/393 quickly i.e. 24024 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 78/57, 11/58, 84/89, 88/393 is 24024.
LCM(78/57, 11/58, 84/89, 88/393) = 24024
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 78/57,11/58,84/89,88/393
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 78,11,84,88
Least Common Multiple of Numerators i.e. LCM of 78,11,84,88 is 24024.
GCF of Denominators means GCF of 57,58,89,393 as per the given fractions.
GCF of 57,58,89,393 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 78,11,84,88
2 | 78, 11, 84, 88 |
2 | 39, 11, 42, 44 |
3 | 39, 11, 21, 22 |
11 | 13, 11, 7, 22 |
13, 1, 7, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 11 x 13 x 1 x 7 x 2 = 24024
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 78,11,84,88 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,11,84,88) = 1
common factors(in case of two or more numbers have common factors) = 264
GCF(78,11,84,88) x common factors =1 x 264 = 264
LCM(78,11,84,88) = ( 78 × 11 × 84 × 88 ) / 264
LCM(78,11,84,88) = 6342336 / 264
LCM(78,11,84,88) = 24024
Lets's calculate GCF of 57,58,89,393
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 24024/1
Therefore the LCM of Fractions 78/57,11/58,84/89,88/393 is 24024
