Know Least Common Multiple of fractions 39/88, 81/74, 270/20 quickly i.e. 5265 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 39/88, 81/74, 270/20 is 5265.
LCM(39/88, 81/74, 270/20) = 5265
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 39/88,81/74,270/20
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 39,81,270
Least Common Multiple of Numerators i.e. LCM of 39,81,270 is 10530.
GCF of Denominators means GCF of 88,74,20 as per the given fractions.
GCF of 88,74,20 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 39,81,270
3 | 39, 81, 270 |
3 | 13, 27, 90 |
3 | 13, 9, 30 |
13, 3, 10 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 13 x 3 x 10 = 10530
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 39,81,270 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,81,270) = 3
common factors(in case of two or more numbers have common factors) = 27
GCF(39,81,270) x common factors =3 x 27 = 81
LCM(39,81,270) = ( 39 × 81 × 270 ) / 81
LCM(39,81,270) = 852930 / 81
LCM(39,81,270) = 10530
Lets's calculate GCF of 88,74,20
2 | 88, 74, 20 |
44, 37, 10 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 10530/2
Therefore the LCM of Fractions 39/88,81/74,270/20 is 5265
