Know Least Common Multiple of fractions 840/36, 3969/885 quickly i.e. 52920 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 840/36, 3969/885 is 52920.
LCM(840/36, 3969/885) = 52920
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 840/36,3969/885
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 840,3969
Least Common Multiple of Numerators i.e. LCM of 840,3969 is 158760.
GCF of Denominators means GCF of 36,885 as per the given fractions.
GCF of 36,885 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 840,3969
3 | 840, 3969 |
7 | 280, 1323 |
40, 189 |
∴ So the LCM of the given numbers is 3 x 7 x 40 x 189 = 158760
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 840,3969 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(840,3969) = 21
common factors(in case of two or more numbers have common factors) = 1
GCF(840,3969) x common factors =21 x 1 = 21
LCM(840,3969) = ( 840 × 3969 ) / 21
LCM(840,3969) = 3333960 / 21
LCM(840,3969) = 158760
Lets's calculate GCF of 36,885
3 | 36, 885 |
12, 295 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 158760/3
Therefore the LCM of Fractions 840/36,3969/885 is 52920
