Know Least Common Multiple of fractions 74/480, 78/434 quickly i.e. 1443 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 74/480, 78/434 is 1443.
LCM(74/480, 78/434) = 1443
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 74/480,78/434
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 74,78
Least Common Multiple of Numerators i.e. LCM of 74,78 is 2886.
GCF of Denominators means GCF of 480,434 as per the given fractions.
GCF of 480,434 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 74,78
2 | 74, 78 |
37, 39 |
∴ So the LCM of the given numbers is 2 x 37 x 39 = 2886
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 74,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,78) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(74,78) x common factors =2 x 1 = 2
LCM(74,78) = ( 74 × 78 ) / 2
LCM(74,78) = 5772 / 2
LCM(74,78) = 2886
Lets's calculate GCF of 480,434
2 | 480, 434 |
240, 217 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2886/2
Therefore the LCM of Fractions 74/480,78/434 is 1443
