Know Least Common Multiple of fractions 306/72, 680/14, 390/454 quickly i.e. 39780 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 306/72, 680/14, 390/454 is 39780.
LCM(306/72, 680/14, 390/454) = 39780
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 306/72,680/14,390/454
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 306,680,390
Least Common Multiple of Numerators i.e. LCM of 306,680,390 is 79560.
GCF of Denominators means GCF of 72,14,454 as per the given fractions.
GCF of 72,14,454 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 306,680,390
2 | 306, 680, 390 |
3 | 153, 340, 195 |
5 | 51, 340, 65 |
17 | 51, 68, 13 |
3, 4, 13 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 17 x 3 x 4 x 13 = 79560
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 306,680,390 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(306,680,390) = 2
common factors(in case of two or more numbers have common factors) = 510
GCF(306,680,390) x common factors =2 x 510 = 1020
LCM(306,680,390) = ( 306 × 680 × 390 ) / 1020
LCM(306,680,390) = 81151200 / 1020
LCM(306,680,390) = 79560
Lets's calculate GCF of 72,14,454
2 | 72, 14, 454 |
36, 7, 227 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 79560/2
Therefore the LCM of Fractions 306/72,680/14,390/454 is 39780
