Know Least Common Multiple of fractions 3942/431, 7885/405 quickly i.e. 31082670 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 3942/431, 7885/405 is 31082670.
LCM(3942/431, 7885/405) = 31082670
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 3942/431,7885/405
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 3942,7885
Least Common Multiple of Numerators i.e. LCM of 3942,7885 is 31082670.
GCF of Denominators means GCF of 431,405 as per the given fractions.
GCF of 431,405 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 3942,7885
Given numbers has no common factors except 1. So, there LCM is their product i.e 31082670
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 3942,7885 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(3942,7885) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(3942,7885) x common factors =1 x 1 = 1
LCM(3942,7885) = ( 3942 × 7885 ) / 1
LCM(3942,7885) = 31082670 / 1
LCM(3942,7885) = 31082670
Lets's calculate GCF of 431,405
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 31082670/1
Therefore the LCM of Fractions 3942/431,7885/405 is 31082670
