Know Least Common Multiple of fractions 17/42, 434/68, 656/268 quickly i.e. 1209992 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 17/42, 434/68, 656/268 is 1209992.
LCM(17/42, 434/68, 656/268) = 1209992
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 17/42,434/68,656/268
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 17,434,656
Least Common Multiple of Numerators i.e. LCM of 17,434,656 is 2419984.
GCF of Denominators means GCF of 42,68,268 as per the given fractions.
GCF of 42,68,268 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 17,434,656
2 | 17, 434, 656 |
17, 217, 328 |
∴ So the LCM of the given numbers is 2 x 17 x 217 x 328 = 2419984
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 17,434,656 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,434,656) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(17,434,656) x common factors =1 x 2 = 2
LCM(17,434,656) = ( 17 × 434 × 656 ) / 2
LCM(17,434,656) = 4839968 / 2
LCM(17,434,656) = 2419984
Lets's calculate GCF of 42,68,268
2 | 42, 68, 268 |
21, 34, 134 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2419984/2
Therefore the LCM of Fractions 17/42,434/68,656/268 is 1209992
