Know Least Common Multiple of fractions 21/124, 30/834, 231/126 quickly i.e. 1155 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 21/124, 30/834, 231/126 is 1155.
LCM(21/124, 30/834, 231/126) = 1155
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 21/124,30/834,231/126
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 21,30,231
Least Common Multiple of Numerators i.e. LCM of 21,30,231 is 2310.
GCF of Denominators means GCF of 124,834,126 as per the given fractions.
GCF of 124,834,126 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 21,30,231
3 | 21, 30, 231 |
7 | 7, 10, 77 |
1, 10, 11 |
∴ So the LCM of the given numbers is 3 x 7 x 1 x 10 x 11 = 2310
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 21,30,231 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,30,231) = 3
common factors(in case of two or more numbers have common factors) = 21
GCF(21,30,231) x common factors =3 x 21 = 63
LCM(21,30,231) = ( 21 × 30 × 231 ) / 63
LCM(21,30,231) = 145530 / 63
LCM(21,30,231) = 2310
Lets's calculate GCF of 124,834,126
2 | 124, 834, 126 |
62, 417, 63 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2310/2
Therefore the LCM of Fractions 21/124,30/834,231/126 is 1155
