Know Least Common Multiple of fractions 21/405, 681/662, 692/481 quickly i.e. 3298764 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 21/405, 681/662, 692/481 is 3298764.
LCM(21/405, 681/662, 692/481) = 3298764
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 21/405,681/662,692/481
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 21,681,692
Least Common Multiple of Numerators i.e. LCM of 21,681,692 is 3298764.
GCF of Denominators means GCF of 405,662,481 as per the given fractions.
GCF of 405,662,481 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 21,681,692
3 | 21, 681, 692 |
7, 227, 692 |
∴ So the LCM of the given numbers is 3 x 7 x 227 x 692 = 3298764
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 21,681,692 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,681,692) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(21,681,692) x common factors =1 x 3 = 3
LCM(21,681,692) = ( 21 × 681 × 692 ) / 3
LCM(21,681,692) = 9896292 / 3
LCM(21,681,692) = 3298764
Lets's calculate GCF of 405,662,481
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3298764/1
Therefore the LCM of Fractions 21/405,681/662,692/481 is 3298764
