Know Least Common Multiple of fractions 390/69, 401/12, 309/534 quickly i.e. 5369390 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 390/69, 401/12, 309/534 is 5369390.
LCM(390/69, 401/12, 309/534) = 5369390
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 390/69,401/12,309/534
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 390,401,309
Least Common Multiple of Numerators i.e. LCM of 390,401,309 is 16108170.
GCF of Denominators means GCF of 69,12,534 as per the given fractions.
GCF of 69,12,534 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 390,401,309
3 | 390, 401, 309 |
130, 401, 103 |
∴ So the LCM of the given numbers is 3 x 130 x 401 x 103 = 16108170
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 390,401,309 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,401,309) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(390,401,309) x common factors =1 x 3 = 3
LCM(390,401,309) = ( 390 × 401 × 309 ) / 3
LCM(390,401,309) = 48324510 / 3
LCM(390,401,309) = 16108170
Lets's calculate GCF of 69,12,534
3 | 69, 12, 534 |
23, 4, 178 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 16108170/3
Therefore the LCM of Fractions 390/69,401/12,309/534 is 5369390
