Know Least Common Multiple of fractions 6/51, 9/89, 21/88, 42/399 quickly i.e. 126 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 6/51, 9/89, 21/88, 42/399 is 126.
LCM(6/51, 9/89, 21/88, 42/399) = 126
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 6/51,9/89,21/88,42/399
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 6,9,21,42
Least Common Multiple of Numerators i.e. LCM of 6,9,21,42 is 126.
GCF of Denominators means GCF of 51,89,88,399 as per the given fractions.
GCF of 51,89,88,399 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 6,9,21,42
2 | 6, 9, 21, 42 |
3 | 3, 9, 21, 21 |
7 | 1, 3, 7, 7 |
1, 3, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 3 x 1 x 1 = 126
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 6,9,21,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(6,9,21,42) = 3
common factors(in case of two or more numbers have common factors) = 126
GCF(6,9,21,42) x common factors =3 x 126 = 378
LCM(6,9,21,42) = ( 6 × 9 × 21 × 42 ) / 378
LCM(6,9,21,42) = 47628 / 378
LCM(6,9,21,42) = 126
Lets's calculate GCF of 51,89,88,399
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 126/1
Therefore the LCM of Fractions 6/51,9/89,21/88,42/399 is 126
