Know Least Common Multiple of fractions 74/81, 48/40, 415/988 quickly i.e. 737040 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 74/81, 48/40, 415/988 is 737040.
LCM(74/81, 48/40, 415/988) = 737040
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 74/81,48/40,415/988
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 74,48,415
Least Common Multiple of Numerators i.e. LCM of 74,48,415 is 737040.
GCF of Denominators means GCF of 81,40,988 as per the given fractions.
GCF of 81,40,988 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 74,48,415
2 | 74, 48, 415 |
37, 24, 415 |
∴ So the LCM of the given numbers is 2 x 37 x 24 x 415 = 737040
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 74,48,415 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,48,415) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(74,48,415) x common factors =1 x 2 = 2
LCM(74,48,415) = ( 74 × 48 × 415 ) / 2
LCM(74,48,415) = 1474080 / 2
LCM(74,48,415) = 737040
Lets's calculate GCF of 81,40,988
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 737040/1
Therefore the LCM of Fractions 74/81,48/40,415/988 is 737040
