Know Least Common Multiple of fractions 14/20, 13/45, 84/34, 69/123 quickly i.e. 25116 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 14/20, 13/45, 84/34, 69/123 is 25116.
LCM(14/20, 13/45, 84/34, 69/123) = 25116
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 14/20,13/45,84/34,69/123
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 14,13,84,69
Least Common Multiple of Numerators i.e. LCM of 14,13,84,69 is 25116.
GCF of Denominators means GCF of 20,45,34,123 as per the given fractions.
GCF of 20,45,34,123 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 14,13,84,69
2 | 14, 13, 84, 69 |
3 | 7, 13, 42, 69 |
7 | 7, 13, 14, 23 |
1, 13, 2, 23 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 13 x 2 x 23 = 25116
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 14,13,84,69 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,13,84,69) = 1
common factors(in case of two or more numbers have common factors) = 42
GCF(14,13,84,69) x common factors =1 x 42 = 42
LCM(14,13,84,69) = ( 14 × 13 × 84 × 69 ) / 42
LCM(14,13,84,69) = 1054872 / 42
LCM(14,13,84,69) = 25116
Lets's calculate GCF of 20,45,34,123
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 25116/1
Therefore the LCM of Fractions 14/20,13/45,84/34,69/123 is 25116
