Know Least Common Multiple of fractions 288/21, 419/35, 679/392 quickly i.e. 11705184 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 288/21, 419/35, 679/392 is 11705184.
LCM(288/21, 419/35, 679/392) = 11705184
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 288/21,419/35,679/392
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 288,419,679
Least Common Multiple of Numerators i.e. LCM of 288,419,679 is 81936288.
GCF of Denominators means GCF of 21,35,392 as per the given fractions.
GCF of 21,35,392 is 7 as it is the largest common factor for these numbers.
Lets's calculate LCM of 288,419,679
Given numbers has no common factors except 1. So, there LCM is their product i.e 81936288
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 288,419,679 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(288,419,679) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(288,419,679) x common factors =1 x 1 = 1
LCM(288,419,679) = ( 288 × 419 × 679 ) / 1
LCM(288,419,679) = 81936288 / 1
LCM(288,419,679) = 81936288
Lets's calculate GCF of 21,35,392
7 | 21, 35, 392 |
3, 5, 56 |
∴ So the GCF of the given numbers is 7 = 7
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 81936288/7
Therefore the LCM of Fractions 288/21,419/35,679/392 is 11705184
