Least Common Multiple (LCM) of 19/97, 84/94, 39/72 is 20748.
LCM(19/97, 84/94, 39/72) = 20748
LCM of 19/97, 84/94, 39/72
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 19/97,84/94,39/72
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 19,84,39
Least Common Multiple of Numerators i.e. LCM of 19,84,39 is 20748.
GCF of Denominators means GCF of 97,94,72 as per the given fractions.
GCF of 97,94,72 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 19,84,39
LCM of Fractions 19/97,84/94,39/72 is 20748
| 3 | 19, 84, 39 |
| 19, 28, 13 |
∴ So the LCM of the given numbers is 3 x 19 x 28 x 13 = 20748
Least Common Multiple of 19,84,39 with GCF Formula
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 19,84,39 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,84,39) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(19,84,39) x common factors =1 x 3 = 3
LCM(19,84,39) = ( 19 × 84 × 39 ) / 3
LCM(19,84,39) = 62244 / 3
LCM(19,84,39) = 20748
Lets's calculate GCF of 97,94,72
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 20748/1
Therefore the LCM of Fractions 19/97,84/94,39/72 is 20748
