Know Least Common Multiple of fractions 83/638, 83/520, 509/749 quickly i.e. 42247 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 83/638, 83/520, 509/749 is 42247.
LCM(83/638, 83/520, 509/749) = 42247
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 83/638,83/520,509/749
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 83,83,509
Least Common Multiple of Numerators i.e. LCM of 83,83,509 is 42247.
GCF of Denominators means GCF of 638,520,749 as per the given fractions.
GCF of 638,520,749 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 83,83,509
83 | 83, 83, 509 |
1, 1, 509 |
∴ So the LCM of the given numbers is 83 x 1 x 1 x 509 = 42247
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 83,83,509 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,83,509) = 1
common factors(in case of two or more numbers have common factors) = 83
GCF(83,83,509) x common factors =1 x 83 = 83
LCM(83,83,509) = ( 83 × 83 × 509 ) / 83
LCM(83,83,509) = 3506501 / 83
LCM(83,83,509) = 42247
Lets's calculate GCF of 638,520,749
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 42247/1
Therefore the LCM of Fractions 83/638,83/520,509/749 is 42247
