Know Least Common Multiple of fractions 46/90, 12/96, 26/38, 78/792 quickly i.e. 1794 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 46/90, 12/96, 26/38, 78/792 is 1794.
LCM(46/90, 12/96, 26/38, 78/792) = 1794
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 46/90,12/96,26/38,78/792
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 46,12,26,78
Least Common Multiple of Numerators i.e. LCM of 46,12,26,78 is 3588.
GCF of Denominators means GCF of 90,96,38,792 as per the given fractions.
GCF of 90,96,38,792 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 46,12,26,78
2 | 46, 12, 26, 78 |
3 | 23, 6, 13, 39 |
13 | 23, 2, 13, 13 |
23, 2, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 23 x 2 x 1 x 1 = 3588
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 46,12,26,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(46,12,26,78) = 2
common factors(in case of two or more numbers have common factors) = 156
GCF(46,12,26,78) x common factors =2 x 156 = 312
LCM(46,12,26,78) = ( 46 × 12 × 26 × 78 ) / 312
LCM(46,12,26,78) = 1119456 / 312
LCM(46,12,26,78) = 3588
Lets's calculate GCF of 90,96,38,792
2 | 90, 96, 38, 792 |
45, 48, 19, 396 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3588/2
Therefore the LCM of Fractions 46/90,12/96,26/38,78/792 is 1794
