Know Least Common Multiple of fractions 108/981, 972/871 quickly i.e. 972 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 108/981, 972/871 is 972.
LCM(108/981, 972/871) = 972
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 108/981,972/871
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 108,972
Least Common Multiple of Numerators i.e. LCM of 108,972 is 972.
GCF of Denominators means GCF of 981,871 as per the given fractions.
GCF of 981,871 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 108,972
2 | 108, 972 |
2 | 54, 486 |
3 | 27, 243 |
3 | 9, 81 |
3 | 3, 27 |
1, 9 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 3 x 1 x 9 = 972
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 108,972 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(108,972) = 108
common factors(in case of two or more numbers have common factors) = 1
GCF(108,972) x common factors =108 x 1 = 108
LCM(108,972) = ( 108 × 972 ) / 108
LCM(108,972) = 104976 / 108
LCM(108,972) = 972
Lets's calculate GCF of 981,871
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 972/1
Therefore the LCM of Fractions 108/981,972/871 is 972
