Know Least Common Multiple of fractions 20/63, 43/969, 414/198 quickly i.e. 59340 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 20/63, 43/969, 414/198 is 59340.
LCM(20/63, 43/969, 414/198) = 59340
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 20/63,43/969,414/198
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 20,43,414
Least Common Multiple of Numerators i.e. LCM of 20,43,414 is 178020.
GCF of Denominators means GCF of 63,969,198 as per the given fractions.
GCF of 63,969,198 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 20,43,414
2 | 20, 43, 414 |
10, 43, 207 |
∴ So the LCM of the given numbers is 2 x 10 x 43 x 207 = 178020
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 20,43,414 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,43,414) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(20,43,414) x common factors =1 x 2 = 2
LCM(20,43,414) = ( 20 × 43 × 414 ) / 2
LCM(20,43,414) = 356040 / 2
LCM(20,43,414) = 178020
Lets's calculate GCF of 63,969,198
3 | 63, 969, 198 |
21, 323, 66 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 178020/3
Therefore the LCM of Fractions 20/63,43/969,414/198 is 59340
