Know Least Common Multiple of fractions 931/781, 8379/855 quickly i.e. 8379 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 931/781, 8379/855 is 8379.
LCM(931/781, 8379/855) = 8379
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 931/781,8379/855
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 931,8379
Least Common Multiple of Numerators i.e. LCM of 931,8379 is 8379.
GCF of Denominators means GCF of 781,855 as per the given fractions.
GCF of 781,855 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 931,8379
7 | 931, 8379 |
7 | 133, 1197 |
19 | 19, 171 |
1, 9 |
∴ So the LCM of the given numbers is 7 x 7 x 19 x 1 x 9 = 8379
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 931,8379 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(931,8379) = 931
common factors(in case of two or more numbers have common factors) = 1
GCF(931,8379) x common factors =931 x 1 = 931
LCM(931,8379) = ( 931 × 8379 ) / 931
LCM(931,8379) = 7800849 / 931
LCM(931,8379) = 8379
Lets's calculate GCF of 781,855
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 8379/1
Therefore the LCM of Fractions 931/781,8379/855 is 8379
