Know Least Common Multiple of fractions 55/21, 928/46, 387/131 quickly i.e. 19752480 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 55/21, 928/46, 387/131 is 19752480.
LCM(55/21, 928/46, 387/131) = 19752480
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 55/21,928/46,387/131
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 55,928,387
Least Common Multiple of Numerators i.e. LCM of 55,928,387 is 19752480.
GCF of Denominators means GCF of 21,46,131 as per the given fractions.
GCF of 21,46,131 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 55,928,387
Given numbers has no common factors except 1. So, there LCM is their product i.e 19752480
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 55,928,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,928,387) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(55,928,387) x common factors =1 x 1 = 1
LCM(55,928,387) = ( 55 × 928 × 387 ) / 1
LCM(55,928,387) = 19752480 / 1
LCM(55,928,387) = 19752480
Lets's calculate GCF of 21,46,131
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 19752480/1
Therefore the LCM of Fractions 55/21,928/46,387/131 is 19752480
