Know Least Common Multiple of fractions 3825/28, 2018/646 quickly i.e. 3859425 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 3825/28, 2018/646 is 3859425.
LCM(3825/28, 2018/646) = 3859425
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 3825/28,2018/646
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 3825,2018
Least Common Multiple of Numerators i.e. LCM of 3825,2018 is 7718850.
GCF of Denominators means GCF of 28,646 as per the given fractions.
GCF of 28,646 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 3825,2018
Given numbers has no common factors except 1. So, there LCM is their product i.e 7718850
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 3825,2018 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(3825,2018) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(3825,2018) x common factors =1 x 1 = 1
LCM(3825,2018) = ( 3825 × 2018 ) / 1
LCM(3825,2018) = 7718850 / 1
LCM(3825,2018) = 7718850
Lets's calculate GCF of 28,646
2 | 28, 646 |
14, 323 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7718850/2
Therefore the LCM of Fractions 3825/28,2018/646 is 3859425
