Know Least Common Multiple of fractions 300/28, 300/34, 121/54 quickly i.e. 18150 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 300/28, 300/34, 121/54 is 18150.
LCM(300/28, 300/34, 121/54) = 18150
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 300/28,300/34,121/54
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 300,300,121
Least Common Multiple of Numerators i.e. LCM of 300,300,121 is 36300.
GCF of Denominators means GCF of 28,34,54 as per the given fractions.
GCF of 28,34,54 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 300,300,121
2 | 300, 300, 121 |
2 | 150, 150, 121 |
3 | 75, 75, 121 |
5 | 25, 25, 121 |
5 | 5, 5, 121 |
1, 1, 121 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 5 x 1 x 1 x 121 = 36300
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 300,300,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(300,300,121) = 1
common factors(in case of two or more numbers have common factors) = 300
GCF(300,300,121) x common factors =1 x 300 = 300
LCM(300,300,121) = ( 300 × 300 × 121 ) / 300
LCM(300,300,121) = 10890000 / 300
LCM(300,300,121) = 36300
Lets's calculate GCF of 28,34,54
2 | 28, 34, 54 |
14, 17, 27 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 36300/2
Therefore the LCM of Fractions 300/28,300/34,121/54 is 18150
