Know Least Common Multiple of fractions 40/388, 820/768, 281/256 quickly i.e. 115210 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 40/388, 820/768, 281/256 is 115210.
LCM(40/388, 820/768, 281/256) = 115210
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 40/388,820/768,281/256
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 40,820,281
Least Common Multiple of Numerators i.e. LCM of 40,820,281 is 460840.
GCF of Denominators means GCF of 388,768,256 as per the given fractions.
GCF of 388,768,256 is 4 as it is the largest common factor for these numbers.
Lets's calculate LCM of 40,820,281
2 | 40, 820, 281 |
2 | 20, 410, 281 |
5 | 10, 205, 281 |
2, 41, 281 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 2 x 41 x 281 = 460840
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 40,820,281 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,820,281) = 1
common factors(in case of two or more numbers have common factors) = 20
GCF(40,820,281) x common factors =1 x 20 = 20
LCM(40,820,281) = ( 40 × 820 × 281 ) / 20
LCM(40,820,281) = 9216800 / 20
LCM(40,820,281) = 460840
Lets's calculate GCF of 388,768,256
2 | 388, 768, 256 |
2 | 194, 384, 128 |
97, 192, 64 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 460840/4
Therefore the LCM of Fractions 40/388,820/768,281/256 is 115210
