Know Least Common Multiple of fractions 102/24, 145/21, 974/231 quickly i.e. 2400910 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 102/24, 145/21, 974/231 is 2400910.
LCM(102/24, 145/21, 974/231) = 2400910
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 102/24,145/21,974/231
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 102,145,974
Least Common Multiple of Numerators i.e. LCM of 102,145,974 is 7202730.
GCF of Denominators means GCF of 24,21,231 as per the given fractions.
GCF of 24,21,231 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 102,145,974
2 | 102, 145, 974 |
51, 145, 487 |
∴ So the LCM of the given numbers is 2 x 51 x 145 x 487 = 7202730
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 102,145,974 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(102,145,974) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(102,145,974) x common factors =1 x 2 = 2
LCM(102,145,974) = ( 102 × 145 × 974 ) / 2
LCM(102,145,974) = 14405460 / 2
LCM(102,145,974) = 7202730
Lets's calculate GCF of 24,21,231
3 | 24, 21, 231 |
8, 7, 77 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7202730/3
Therefore the LCM of Fractions 102/24,145/21,974/231 is 2400910
