Know Least Common Multiple of fractions 6391/312, 3256/7020 quickly i.e. 1891736/156 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 6391/312, 3256/7020 is 1891736/156.
LCM(6391/312, 3256/7020) = 1891736/156
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 6391/312,3256/7020
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 6391,3256
Least Common Multiple of Numerators i.e. LCM of 6391,3256 is 1891736.
GCF of Denominators means GCF of 312,7020 as per the given fractions.
GCF of 312,7020 is 156 as it is the largest common factor for these numbers.
Lets's calculate LCM of 6391,3256
11 | 6391, 3256 |
581, 296 |
∴ So the LCM of the given numbers is 11 x 581 x 296 = 1891736
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 6391,3256 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(6391,3256) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(6391,3256) x common factors =11 x 1 = 11
LCM(6391,3256) = ( 6391 × 3256 ) / 11
LCM(6391,3256) = 20809096 / 11
LCM(6391,3256) = 1891736
Lets's calculate GCF of 312,7020
2 | 312, 7020 |
2 | 156, 3510 |
3 | 78, 1755 |
13 | 26, 585 |
2, 45 |
∴ So the GCF of the given numbers is 2 x 2 x 3 x 13 = 156
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1891736/156
Therefore the LCM of Fractions 6391/312,3256/7020 is 1891736/156
