Know Least Common Multiple of fractions 390/240, 456/870, 442/195 quickly i.e. 33592 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 390/240, 456/870, 442/195 is 33592.
LCM(390/240, 456/870, 442/195) = 33592
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 390/240,456/870,442/195
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 390,456,442
Least Common Multiple of Numerators i.e. LCM of 390,456,442 is 503880.
GCF of Denominators means GCF of 240,870,195 as per the given fractions.
GCF of 240,870,195 is 15 as it is the largest common factor for these numbers.
Lets's calculate LCM of 390,456,442
2 | 390, 456, 442 |
3 | 195, 228, 221 |
13 | 65, 76, 221 |
5, 76, 17 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 5 x 76 x 17 = 503880
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 390,456,442 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,456,442) = 2
common factors(in case of two or more numbers have common factors) = 78
GCF(390,456,442) x common factors =2 x 78 = 156
LCM(390,456,442) = ( 390 × 456 × 442 ) / 156
LCM(390,456,442) = 78605280 / 156
LCM(390,456,442) = 503880
Lets's calculate GCF of 240,870,195
3 | 240, 870, 195 |
5 | 80, 290, 65 |
16, 58, 13 |
∴ So the GCF of the given numbers is 3 x 5 = 15
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 503880/15
Therefore the LCM of Fractions 390/240,456/870,442/195 is 33592
