Know Least Common Multiple of fractions 2028/77, 2400/561 quickly i.e. 405600/11 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 2028/77, 2400/561 is 405600/11.
LCM(2028/77, 2400/561) = 405600/11
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 2028/77,2400/561
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 2028,2400
Least Common Multiple of Numerators i.e. LCM of 2028,2400 is 405600.
GCF of Denominators means GCF of 77,561 as per the given fractions.
GCF of 77,561 is 11 as it is the largest common factor for these numbers.
Lets's calculate LCM of 2028,2400
2 | 2028, 2400 |
2 | 1014, 1200 |
3 | 507, 600 |
169, 200 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 169 x 200 = 405600
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 2028,2400 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(2028,2400) = 12
common factors(in case of two or more numbers have common factors) = 1
GCF(2028,2400) x common factors =12 x 1 = 12
LCM(2028,2400) = ( 2028 × 2400 ) / 12
LCM(2028,2400) = 4867200 / 12
LCM(2028,2400) = 405600
Lets's calculate GCF of 77,561
11 | 77, 561 |
7, 51 |
∴ So the GCF of the given numbers is 11 = 11
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 405600/11
Therefore the LCM of Fractions 2028/77,2400/561 is 405600/11
