Know Least Common Multiple of fractions 20/455, 3518/4990 quickly i.e. 7036 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 20/455, 3518/4990 is 7036.
LCM(20/455, 3518/4990) = 7036
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 20/455,3518/4990
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 20,3518
Least Common Multiple of Numerators i.e. LCM of 20,3518 is 35180.
GCF of Denominators means GCF of 455,4990 as per the given fractions.
GCF of 455,4990 is 5 as it is the largest common factor for these numbers.
Lets's calculate LCM of 20,3518
2 | 20, 3518 |
10, 1759 |
∴ So the LCM of the given numbers is 2 x 10 x 1759 = 35180
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 20,3518 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,3518) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(20,3518) x common factors =2 x 1 = 2
LCM(20,3518) = ( 20 × 3518 ) / 2
LCM(20,3518) = 70360 / 2
LCM(20,3518) = 35180
Lets's calculate GCF of 455,4990
5 | 455, 4990 |
91, 998 |
∴ So the GCF of the given numbers is 5 = 5
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 35180/5
Therefore the LCM of Fractions 20/455,3518/4990 is 7036
