Know Least Common Multiple of fractions 43/74, 16/11, 784/987 quickly i.e. 33712 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 43/74, 16/11, 784/987 is 33712.
LCM(43/74, 16/11, 784/987) = 33712
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 43/74,16/11,784/987
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 43,16,784
Least Common Multiple of Numerators i.e. LCM of 43,16,784 is 33712.
GCF of Denominators means GCF of 74,11,987 as per the given fractions.
GCF of 74,11,987 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 43,16,784
2 | 43, 16, 784 |
2 | 43, 8, 392 |
2 | 43, 4, 196 |
2 | 43, 2, 98 |
43, 1, 49 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 43 x 1 x 49 = 33712
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 43,16,784 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(43,16,784) = 1
common factors(in case of two or more numbers have common factors) = 16
GCF(43,16,784) x common factors =1 x 16 = 16
LCM(43,16,784) = ( 43 × 16 × 784 ) / 16
LCM(43,16,784) = 539392 / 16
LCM(43,16,784) = 33712
Lets's calculate GCF of 74,11,987
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 33712/1
Therefore the LCM of Fractions 43/74,16/11,784/987 is 33712
