Know Least Common Multiple of fractions 400/28, 188/5621 quickly i.e. 18800/7 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 400/28, 188/5621 is 18800/7.
LCM(400/28, 188/5621) = 18800/7
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 400/28,188/5621
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 400,188
Least Common Multiple of Numerators i.e. LCM of 400,188 is 18800.
GCF of Denominators means GCF of 28,5621 as per the given fractions.
GCF of 28,5621 is 7 as it is the largest common factor for these numbers.
Lets's calculate LCM of 400,188
2 | 400, 188 |
2 | 200, 94 |
100, 47 |
∴ So the LCM of the given numbers is 2 x 2 x 100 x 47 = 18800
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 400,188 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(400,188) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(400,188) x common factors =4 x 1 = 4
LCM(400,188) = ( 400 × 188 ) / 4
LCM(400,188) = 75200 / 4
LCM(400,188) = 18800
Lets's calculate GCF of 28,5621
7 | 28, 5621 |
4, 803 |
∴ So the GCF of the given numbers is 7 = 7
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 18800/7
Therefore the LCM of Fractions 400/28,188/5621 is 18800/7
