Know Least Common Multiple of fractions 400/90, 194/25, 379/385 quickly i.e. 2941040 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 400/90, 194/25, 379/385 is 2941040.
LCM(400/90, 194/25, 379/385) = 2941040
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 400/90,194/25,379/385
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 400,194,379
Least Common Multiple of Numerators i.e. LCM of 400,194,379 is 14705200.
GCF of Denominators means GCF of 90,25,385 as per the given fractions.
GCF of 90,25,385 is 5 as it is the largest common factor for these numbers.
Lets's calculate LCM of 400,194,379
2 | 400, 194, 379 |
200, 97, 379 |
∴ So the LCM of the given numbers is 2 x 200 x 97 x 379 = 14705200
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 400,194,379 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(400,194,379) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(400,194,379) x common factors =1 x 2 = 2
LCM(400,194,379) = ( 400 × 194 × 379 ) / 2
LCM(400,194,379) = 29410400 / 2
LCM(400,194,379) = 14705200
Lets's calculate GCF of 90,25,385
5 | 90, 25, 385 |
18, 5, 77 |
∴ So the GCF of the given numbers is 5 = 5
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 14705200/5
Therefore the LCM of Fractions 400/90,194/25,379/385 is 2941040
