Know Least Common Multiple of fractions 55/83, 56/13, 60/80, 64/103 quickly i.e. 73920 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 55/83, 56/13, 60/80, 64/103 is 73920.
LCM(55/83, 56/13, 60/80, 64/103) = 73920
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 55/83,56/13,60/80,64/103
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 55,56,60,64
Least Common Multiple of Numerators i.e. LCM of 55,56,60,64 is 73920.
GCF of Denominators means GCF of 83,13,80,103 as per the given fractions.
GCF of 83,13,80,103 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 55,56,60,64
2 | 55, 56, 60, 64 |
2 | 55, 28, 30, 32 |
2 | 55, 14, 15, 16 |
5 | 55, 7, 15, 8 |
11, 7, 3, 8 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 11 x 7 x 3 x 8 = 73920
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 55,56,60,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,56,60,64) = 1
common factors(in case of two or more numbers have common factors) = 160
GCF(55,56,60,64) x common factors =1 x 160 = 160
LCM(55,56,60,64) = ( 55 × 56 × 60 × 64 ) / 160
LCM(55,56,60,64) = 11827200 / 160
LCM(55,56,60,64) = 73920
Lets's calculate GCF of 83,13,80,103
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 73920/1
Therefore the LCM of Fractions 55/83,56/13,60/80,64/103 is 73920
