Know Least Common Multiple of fractions 13/840, 12/840, 156/184 quickly i.e. 156/8 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 13/840, 12/840, 156/184 is 156/8.
LCM(13/840, 12/840, 156/184) = 156/8
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 13/840,12/840,156/184
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 13,12,156
Least Common Multiple of Numerators i.e. LCM of 13,12,156 is 156.
GCF of Denominators means GCF of 840,840,184 as per the given fractions.
GCF of 840,840,184 is 8 as it is the largest common factor for these numbers.
Lets's calculate LCM of 13,12,156
2 | 13, 12, 156 |
2 | 13, 6, 78 |
3 | 13, 3, 39 |
13 | 13, 1, 13 |
1, 1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 13 x 1 x 1 x 1 = 156
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 13,12,156 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,12,156) = 1
common factors(in case of two or more numbers have common factors) = 156
GCF(13,12,156) x common factors =1 x 156 = 156
LCM(13,12,156) = ( 13 × 12 × 156 ) / 156
LCM(13,12,156) = 24336 / 156
LCM(13,12,156) = 156
Lets's calculate GCF of 840,840,184
2 | 840, 840, 184 |
2 | 420, 420, 92 |
2 | 210, 210, 46 |
105, 105, 23 |
∴ So the GCF of the given numbers is 2 x 2 x 2 = 8
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 156/8
Therefore the LCM of Fractions 13/840,12/840,156/184 is 156/8
