Know Least Common Multiple of fractions 390/86, 658/4186 quickly i.e. 64155 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 390/86, 658/4186 is 64155.
LCM(390/86, 658/4186) = 64155
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 390/86,658/4186
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 390,658
Least Common Multiple of Numerators i.e. LCM of 390,658 is 128310.
GCF of Denominators means GCF of 86,4186 as per the given fractions.
GCF of 86,4186 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 390,658
2 | 390, 658 |
195, 329 |
∴ So the LCM of the given numbers is 2 x 195 x 329 = 128310
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 390,658 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,658) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(390,658) x common factors =2 x 1 = 2
LCM(390,658) = ( 390 × 658 ) / 2
LCM(390,658) = 256620 / 2
LCM(390,658) = 128310
Lets's calculate GCF of 86,4186
2 | 86, 4186 |
43, 2093 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 128310/2
Therefore the LCM of Fractions 390/86,658/4186 is 64155
