Know Least Common Multiple of fractions 3979/830, 9671/1790 quickly i.e. 38480909/10 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 3979/830, 9671/1790 is 38480909/10.
LCM(3979/830, 9671/1790) = 38480909/10
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 3979/830,9671/1790
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 3979,9671
Least Common Multiple of Numerators i.e. LCM of 3979,9671 is 38480909.
GCF of Denominators means GCF of 830,1790 as per the given fractions.
GCF of 830,1790 is 10 as it is the largest common factor for these numbers.
Lets's calculate LCM of 3979,9671
Given numbers has no common factors except 1. So, there LCM is their product i.e 38480909
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 3979,9671 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(3979,9671) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(3979,9671) x common factors =1 x 1 = 1
LCM(3979,9671) = ( 3979 × 9671 ) / 1
LCM(3979,9671) = 38480909 / 1
LCM(3979,9671) = 38480909
Lets's calculate GCF of 830,1790
2 | 830, 1790 |
5 | 415, 895 |
83, 179 |
∴ So the GCF of the given numbers is 2 x 5 = 10
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 38480909/10
Therefore the LCM of Fractions 3979/830,9671/1790 is 38480909/10
