Know Least Common Multiple of fractions 90/891, 2556/2869 quickly i.e. 12780 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 90/891, 2556/2869 is 12780.
LCM(90/891, 2556/2869) = 12780
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 90/891,2556/2869
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 90,2556
Least Common Multiple of Numerators i.e. LCM of 90,2556 is 12780.
GCF of Denominators means GCF of 891,2869 as per the given fractions.
GCF of 891,2869 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 90,2556
2 | 90, 2556 |
3 | 45, 1278 |
3 | 15, 426 |
5, 142 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 142 = 12780
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 90,2556 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,2556) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(90,2556) x common factors =18 x 1 = 18
LCM(90,2556) = ( 90 × 2556 ) / 18
LCM(90,2556) = 230040 / 18
LCM(90,2556) = 12780
Lets's calculate GCF of 891,2869
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 12780/1
Therefore the LCM of Fractions 90/891,2556/2869 is 12780
