Know Least Common Multiple of fractions 640/489, 2604/9702 quickly i.e. 138880 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 640/489, 2604/9702 is 138880.
LCM(640/489, 2604/9702) = 138880
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 640/489,2604/9702
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 640,2604
Least Common Multiple of Numerators i.e. LCM of 640,2604 is 416640.
GCF of Denominators means GCF of 489,9702 as per the given fractions.
GCF of 489,9702 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 640,2604
2 | 640, 2604 |
2 | 320, 1302 |
160, 651 |
∴ So the LCM of the given numbers is 2 x 2 x 160 x 651 = 416640
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 640,2604 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,2604) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(640,2604) x common factors =4 x 1 = 4
LCM(640,2604) = ( 640 × 2604 ) / 4
LCM(640,2604) = 1666560 / 4
LCM(640,2604) = 416640
Lets's calculate GCF of 489,9702
3 | 489, 9702 |
163, 3234 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 416640/3
Therefore the LCM of Fractions 640/489,2604/9702 is 138880
