Know Least Common Multiple of fractions 820/439, 656/686 quickly i.e. 3280 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 820/439, 656/686 is 3280.
LCM(820/439, 656/686) = 3280
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 820/439,656/686
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 820,656
Least Common Multiple of Numerators i.e. LCM of 820,656 is 3280.
GCF of Denominators means GCF of 439,686 as per the given fractions.
GCF of 439,686 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 820,656
2 | 820, 656 |
2 | 410, 328 |
41 | 205, 164 |
5, 4 |
∴ So the LCM of the given numbers is 2 x 2 x 41 x 5 x 4 = 3280
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 820,656 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(820,656) = 164
common factors(in case of two or more numbers have common factors) = 1
GCF(820,656) x common factors =164 x 1 = 164
LCM(820,656) = ( 820 × 656 ) / 164
LCM(820,656) = 537920 / 164
LCM(820,656) = 3280
Lets's calculate GCF of 439,686
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3280/1
Therefore the LCM of Fractions 820/439,656/686 is 3280
