Know Least Common Multiple of fractions 40/72, 19/26, 478/728 quickly i.e. 90820 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 40/72, 19/26, 478/728 is 90820.
LCM(40/72, 19/26, 478/728) = 90820
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 40/72,19/26,478/728
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 40,19,478
Least Common Multiple of Numerators i.e. LCM of 40,19,478 is 181640.
GCF of Denominators means GCF of 72,26,728 as per the given fractions.
GCF of 72,26,728 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 40,19,478
2 | 40, 19, 478 |
20, 19, 239 |
∴ So the LCM of the given numbers is 2 x 20 x 19 x 239 = 181640
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 40,19,478 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,19,478) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(40,19,478) x common factors =1 x 2 = 2
LCM(40,19,478) = ( 40 × 19 × 478 ) / 2
LCM(40,19,478) = 363280 / 2
LCM(40,19,478) = 181640
Lets's calculate GCF of 72,26,728
2 | 72, 26, 728 |
36, 13, 364 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 181640/2
Therefore the LCM of Fractions 40/72,19/26,478/728 is 90820
