Know Least Common Multiple of fractions 111/28, 139/1920 quickly i.e. 15429/4 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 111/28, 139/1920 is 15429/4.
LCM(111/28, 139/1920) = 15429/4
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 111/28,139/1920
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 111,139
Least Common Multiple of Numerators i.e. LCM of 111,139 is 15429.
GCF of Denominators means GCF of 28,1920 as per the given fractions.
GCF of 28,1920 is 4 as it is the largest common factor for these numbers.
Lets's calculate LCM of 111,139
Given numbers has no common factors except 1. So, there LCM is their product i.e 15429
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 111,139 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(111,139) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(111,139) x common factors =1 x 1 = 1
LCM(111,139) = ( 111 × 139 ) / 1
LCM(111,139) = 15429 / 1
LCM(111,139) = 15429
Lets's calculate GCF of 28,1920
2 | 28, 1920 |
2 | 14, 960 |
7, 480 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 15429/4
Therefore the LCM of Fractions 111/28,139/1920 is 15429/4
