Know Least Common Multiple of fractions 55/87, 62/51, 29/21 quickly i.e. 98890/3 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 55/87, 62/51, 29/21 is 98890/3.
LCM(55/87, 62/51, 29/21) = 98890/3
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 55/87,62/51,29/21
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 55,62,29
Least Common Multiple of Numerators i.e. LCM of 55,62,29 is 98890.
GCF of Denominators means GCF of 87,51,21 as per the given fractions.
GCF of 87,51,21 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 55,62,29
Given numbers has no common factors except 1. So, there LCM is their product i.e 98890
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 55,62,29 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,62,29) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(55,62,29) x common factors =1 x 1 = 1
LCM(55,62,29) = ( 55 × 62 × 29 ) / 1
LCM(55,62,29) = 98890 / 1
LCM(55,62,29) = 98890
Lets's calculate GCF of 87,51,21
3 | 87, 51, 21 |
29, 17, 7 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 98890/3
Therefore the LCM of Fractions 55/87,62/51,29/21 is 98890/3
