Know Least Common Multiple of fractions 7876/621, 4574/813 quickly i.e. 18012412/3 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 7876/621, 4574/813 is 18012412/3.
LCM(7876/621, 4574/813) = 18012412/3
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 7876/621,4574/813
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 7876,4574
Least Common Multiple of Numerators i.e. LCM of 7876,4574 is 18012412.
GCF of Denominators means GCF of 621,813 as per the given fractions.
GCF of 621,813 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 7876,4574
2 | 7876, 4574 |
3938, 2287 |
∴ So the LCM of the given numbers is 2 x 3938 x 2287 = 18012412
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 7876,4574 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7876,4574) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(7876,4574) x common factors =2 x 1 = 2
LCM(7876,4574) = ( 7876 × 4574 ) / 2
LCM(7876,4574) = 36024824 / 2
LCM(7876,4574) = 18012412
Lets's calculate GCF of 621,813
3 | 621, 813 |
207, 271 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 18012412/3
Therefore the LCM of Fractions 7876/621,4574/813 is 18012412/3
