Know Least Common Multiple of fractions 42/171, 338/205, 783/988 quickly i.e. 1852578 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 42/171, 338/205, 783/988 is 1852578.
LCM(42/171, 338/205, 783/988) = 1852578
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 42/171,338/205,783/988
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 42,338,783
Least Common Multiple of Numerators i.e. LCM of 42,338,783 is 1852578.
GCF of Denominators means GCF of 171,205,988 as per the given fractions.
GCF of 171,205,988 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 42,338,783
2 | 42, 338, 783 |
3 | 21, 169, 783 |
7, 169, 261 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 169 x 261 = 1852578
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 42,338,783 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,338,783) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(42,338,783) x common factors =1 x 6 = 6
LCM(42,338,783) = ( 42 × 338 × 783 ) / 6
LCM(42,338,783) = 11115468 / 6
LCM(42,338,783) = 1852578
Lets's calculate GCF of 171,205,988
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1852578/1
Therefore the LCM of Fractions 42/171,338/205,783/988 is 1852578
