Know Least Common Multiple of fractions 7/28, 6/38, 69/15, 17/173 quickly i.e. 16422 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 7/28, 6/38, 69/15, 17/173 is 16422.
LCM(7/28, 6/38, 69/15, 17/173) = 16422
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 7/28,6/38,69/15,17/173
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 7,6,69,17
Least Common Multiple of Numerators i.e. LCM of 7,6,69,17 is 16422.
GCF of Denominators means GCF of 28,38,15,173 as per the given fractions.
GCF of 28,38,15,173 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 7,6,69,17
3 | 7, 6, 69, 17 |
7, 2, 23, 17 |
∴ So the LCM of the given numbers is 3 x 7 x 2 x 23 x 17 = 16422
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 7,6,69,17 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7,6,69,17) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(7,6,69,17) x common factors =1 x 3 = 3
LCM(7,6,69,17) = ( 7 × 6 × 69 × 17 ) / 3
LCM(7,6,69,17) = 49266 / 3
LCM(7,6,69,17) = 16422
Lets's calculate GCF of 28,38,15,173
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 16422/1
Therefore the LCM of Fractions 7/28,6/38,69/15,17/173 is 16422
