Know Least Common Multiple of fractions 27/17, 90/67, 23/68, 21/618 quickly i.e. 43470 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 27/17, 90/67, 23/68, 21/618 is 43470.
LCM(27/17, 90/67, 23/68, 21/618) = 43470
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 27/17,90/67,23/68,21/618
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 27,90,23,21
Least Common Multiple of Numerators i.e. LCM of 27,90,23,21 is 43470.
GCF of Denominators means GCF of 17,67,68,618 as per the given fractions.
GCF of 17,67,68,618 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 27,90,23,21
3 | 27, 90, 23, 21 |
3 | 9, 30, 23, 7 |
3, 10, 23, 7 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 10 x 23 x 7 = 43470
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 27,90,23,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(27,90,23,21) = 1
common factors(in case of two or more numbers have common factors) = 27
GCF(27,90,23,21) x common factors =1 x 27 = 27
LCM(27,90,23,21) = ( 27 × 90 × 23 × 21 ) / 27
LCM(27,90,23,21) = 1173690 / 27
LCM(27,90,23,21) = 43470
Lets's calculate GCF of 17,67,68,618
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 43470/1
Therefore the LCM of Fractions 27/17,90/67,23/68,21/618 is 43470
