Know Least Common Multiple of fractions 81/561, 745/207, 212/279 quickly i.e. 4264380 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 81/561, 745/207, 212/279 is 4264380.
LCM(81/561, 745/207, 212/279) = 4264380
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 81/561,745/207,212/279
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 81,745,212
Least Common Multiple of Numerators i.e. LCM of 81,745,212 is 12793140.
GCF of Denominators means GCF of 561,207,279 as per the given fractions.
GCF of 561,207,279 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 81,745,212
Given numbers has no common factors except 1. So, there LCM is their product i.e 12793140
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 81,745,212 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,745,212) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,745,212) x common factors =1 x 1 = 1
LCM(81,745,212) = ( 81 × 745 × 212 ) / 1
LCM(81,745,212) = 12793140 / 1
LCM(81,745,212) = 12793140
Lets's calculate GCF of 561,207,279
3 | 561, 207, 279 |
187, 69, 93 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 12793140/3
Therefore the LCM of Fractions 81/561,745/207,212/279 is 4264380
