Know Least Common Multiple of fractions 21/29, 378/97, 837/401 quickly i.e. 11718 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 21/29, 378/97, 837/401 is 11718.
LCM(21/29, 378/97, 837/401) = 11718
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 21/29,378/97,837/401
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 21,378,837
Least Common Multiple of Numerators i.e. LCM of 21,378,837 is 11718.
GCF of Denominators means GCF of 29,97,401 as per the given fractions.
GCF of 29,97,401 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 21,378,837
3 | 21, 378, 837 |
3 | 7, 126, 279 |
3 | 7, 42, 93 |
7 | 7, 14, 31 |
1, 2, 31 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 7 x 1 x 2 x 31 = 11718
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 21,378,837 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,378,837) = 3
common factors(in case of two or more numbers have common factors) = 189
GCF(21,378,837) x common factors =3 x 189 = 567
LCM(21,378,837) = ( 21 × 378 × 837 ) / 567
LCM(21,378,837) = 6644106 / 567
LCM(21,378,837) = 11718
Lets's calculate GCF of 29,97,401
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 11718/1
Therefore the LCM of Fractions 21/29,378/97,837/401 is 11718
