Know Least Common Multiple of fractions 408/64, 420/88, 693/551 quickly i.e. 471240 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 408/64, 420/88, 693/551 is 471240.
LCM(408/64, 420/88, 693/551) = 471240
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 408/64,420/88,693/551
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 408,420,693
Least Common Multiple of Numerators i.e. LCM of 408,420,693 is 471240.
GCF of Denominators means GCF of 64,88,551 as per the given fractions.
GCF of 64,88,551 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 408,420,693
2 | 408, 420, 693 |
2 | 204, 210, 693 |
3 | 102, 105, 693 |
7 | 34, 35, 231 |
34, 5, 33 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 34 x 5 x 33 = 471240
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 408,420,693 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(408,420,693) = 3
common factors(in case of two or more numbers have common factors) = 84
GCF(408,420,693) x common factors =3 x 84 = 252
LCM(408,420,693) = ( 408 × 420 × 693 ) / 252
LCM(408,420,693) = 118752480 / 252
LCM(408,420,693) = 471240
Lets's calculate GCF of 64,88,551
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 471240/1
Therefore the LCM of Fractions 408/64,420/88,693/551 is 471240
