Know Least Common Multiple of fractions 82/52, 14/15, 28/90, 21/660 quickly i.e. 3444 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 82/52, 14/15, 28/90, 21/660 is 3444.
LCM(82/52, 14/15, 28/90, 21/660) = 3444
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 82/52,14/15,28/90,21/660
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 82,14,28,21
Least Common Multiple of Numerators i.e. LCM of 82,14,28,21 is 3444.
GCF of Denominators means GCF of 52,15,90,660 as per the given fractions.
GCF of 52,15,90,660 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 82,14,28,21
2 | 82, 14, 28, 21 |
7 | 41, 7, 14, 21 |
41, 1, 2, 3 |
∴ So the LCM of the given numbers is 2 x 7 x 41 x 1 x 2 x 3 = 3444
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 82,14,28,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(82,14,28,21) = 1
common factors(in case of two or more numbers have common factors) = 196
GCF(82,14,28,21) x common factors =1 x 196 = 196
LCM(82,14,28,21) = ( 82 × 14 × 28 × 21 ) / 196
LCM(82,14,28,21) = 675024 / 196
LCM(82,14,28,21) = 3444
Lets's calculate GCF of 52,15,90,660
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3444/1
Therefore the LCM of Fractions 82/52,14/15,28/90,21/660 is 3444
