Know Least Common Multiple of fractions 645/838, 620/660, 693/144 quickly i.e. 9237690 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 645/838, 620/660, 693/144 is 9237690.
LCM(645/838, 620/660, 693/144) = 9237690
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 645/838,620/660,693/144
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 645,620,693
Least Common Multiple of Numerators i.e. LCM of 645,620,693 is 18475380.
GCF of Denominators means GCF of 838,660,144 as per the given fractions.
GCF of 838,660,144 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 645,620,693
3 | 645, 620, 693 |
5 | 215, 620, 231 |
43, 124, 231 |
∴ So the LCM of the given numbers is 3 x 5 x 43 x 124 x 231 = 18475380
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 645,620,693 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(645,620,693) = 1
common factors(in case of two or more numbers have common factors) = 15
GCF(645,620,693) x common factors =1 x 15 = 15
LCM(645,620,693) = ( 645 × 620 × 693 ) / 15
LCM(645,620,693) = 277130700 / 15
LCM(645,620,693) = 18475380
Lets's calculate GCF of 838,660,144
2 | 838, 660, 144 |
419, 330, 72 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 18475380/2
Therefore the LCM of Fractions 645/838,620/660,693/144 is 9237690
